One of the OMAP1 clocks can use the fixed divisor recalculation code
introduced in the OMAP2 clock code, so rename the
omap2_fixed_divisor_recalc() function to omap_fixed_divisor_recalc()
and make it available to all OMAPs. A followup patch converts the OMAP1
clock.

AM3505/17 though a OMAP3530 derivative have the following
main differences
- Removal of the following OMAP3 modules
- IVA
- ISP/CAM
- Modem and D2D components (MAD2D, SAD2D)
- USIM
- SSI
- Mailboxes
- USB OTG
- ICR
- MSPRO
- SmartReflex
- SDRC replaced with EMIF4 Controller in the SDRC subsystem
thus adding support for DDR2 memory devices
- Addition of the following new modules
- Ethernet MAC (CPGMAC)
- CAN Controller (HECC)
- New USB OTG Controller with integrated Phy
- Video Processing Front End (VPFE)
- Additional UART (UART4)
- All security accelerators disabled on GP devices and not to
be accessed or configured
This patch defines CPU flags for AM3505/17 and update the clock table.
Clock support for new modules will be added by subsequent patches.

Add CK_* flags for the two new Sitara chips, AM3505 and AM3517, and
the OMAP34xx die shrink, OMAP36xx/OMAP37xx. Introduce a new CK_*
flag, CK_3XXX, that marks all clocks that are common to OMAP3 family
chips. CK_343X now refers to clocks that are available only on
OMAP34{1,2,3,4}0 (WTBU) and OMAP35{03,15,25,30} (any version).
At some point, the RATE_IN_* flags should be updated also.
While here, add some documentation describing the chip families
covered by these clock flags.
This patch is partially based on patches from Ranjith Lohithakshan
<ranjithl@ti.com> and Vishwanath Sripathy <vishwanath.bs@ti.com>.

The first thing that omap2_init_clksel_parent() does is check for
a non-zero .clksel field in the struct clk. Therefore, it is
pointless calling this function on clocks where the clksel field
is unset.
Remove init calls to omap2_init_clksel_parent() on clocks without
a clksel field.

Add necessary definitions to clock framework to allow changing
dpll4_m5_ck rate. This is used by the camera code.

CORE_96M_FCLK
The correct parent of the McBSP 2, 3, and 4 functional clocks is
PER_96M_FCLK, not CORE_96M_FCLK. Fix this in the OMAP clock tree.

UART1 & 2 were missing clockdomains resulting in broken omap_hwmod
init for these devices.

The OMAP3 clock code currently #includes a large .h file full of static
data structures. Instead, define the data in a .c file.
Russell King <linux@arm.linux.org.uk> proposed this new arrangement:
