Use jz4740 timer counter for sched_clock source. This implementation will
give high resolution cputime accounting.

Platforms which use raw zboot images may need to link the image at
a fixed address if there is no other way to communicate the load
address to the bootloader.  Allow the per-platform Kbuild files
to specify an optional zboot image load address (zload-y) and fall
back to calc_vmlinuz_load_addr if unset.

Use the GPIO descriptor API instead of the deprecated legacy GPIO API to
manage the busy GPIO.

The patch updates both the jz4740 nand driver and the only user of the driver
the qi-lb60 board driver.

Fixes sparse warnings:

  arch/mips/jz4740/irq.c:63:6: warning: symbol 'jz4740_irq_suspend' was not declared. Should it be static?
  arch/mips/jz4740/irq.c:69:6: warning: symbol 'jz4740_irq_resume' was not declared. Should it be static?

Also, I've seen some elusive build errors on my automated build test
where JZ4740_IRQ_BASE and NR_IRQS are missing, but I can't reproduce
them manually for some reason. Anyway, mach-jz4740/irq.h should help us
avoid relying on some implicit include.

Pull GPIO update from Linus Walleij:
 "This is the bulk of GPIO changes for the v3.17 development cycle, and
  this time we got a lot of action going on and it will continue:

   - The core GPIO library implementation has been split up in three
     different files:
     - gpiolib.c for the latest and greatest and shiny GPIO library code
       using GPIO descriptors only
     - gpiolib-legacy.c for the old integer number space API that we are
       phasing out gradually
     - gpiolib-sysfs.c for the sysfs interface that we are not entirely
       happy with, but has to live on for ABI compatibility

   - Add a flags argument to *gpiod_get* functions, with some
     backward-compatibility macros to ease transitions.  We should have
     had the flags there from the beginning it seems, now we need to
     clean up the mess.  There is a plan on how to move forward here
     devised by Alexandre Courbot and Mark Brown

   - Split off a special <linux/gpio/machine.h> header for the board
     gpio table registration, as per example from the regulator
     subsystem

   - Start to kill off the return value from gpiochip_remove() by
     removing the __must_check attribute and removing all checks inside
     the drivers/gpio directory.  The rationale is: well what were we
     supposed to do if there is an error code? Not much: print an error
     message.  And gpiolib already does that.  So make this function
     return void eventually

   - Some cleanups of hairy gpiolib code, make some functions not to be
     used outside the library private and make sure they are not
     exported, remove gpiod_lock/unlock_as_irq() as the existing
     function is for driver-internal use and fine as it is, delete
     gpio_ensure_requested() as it is not meaningful anymore

   - Support the GPIOF_ACTIVE_LOW flag from gpio_request_one() function
     calls, which is logical since this is already supported when
     referencing GPIOs from e.g. device trees

   - Switch STMPE, intel-mid, lynxpoint and ACPI (!) to use the gpiolib
     irqchip helpers cutting down on GPIO irqchip boilerplate a bit more

   - New driver for the Zynq GPIO block

   - The usual incremental improvements around a bunch of drivers

   - Janitorial syntactic and semantic cleanups by Jingoo Han, and
     Rickard Strandqvist especially"

Rename usb_nop_xceiv to usb_phy_generic in platform data to match the
name change of the nop transceiver driver in commit 4525bee (usb: phy:
rename usb_nop_xceiv to usb_phy_generic).

The name change induced a kernel panic due to an unhandled kernel
unaligned access while trying to dereference musb->xceiv->io_ops in
musb_init_controller().
