Initialize pp->dev in qcom_pcie_probe() before calling get_resources(),
which uses it.

The qcom driver never uses the platform drvdata pointer, so don't bother
setting it. No functional change intended.

This code is not being built as a module by anyone:
drivers/pci/host/Kconfig:config PCIE_QCOM
drivers/pci/host/Kconfig: bool "Qualcomm PCIe controller"
Remove uses of MODULE_DESCRIPTION(), MODULE_AUTHOR(), MODULE_LICENSE(),
etc., so that when reading the driver there is no doubt it is builtin-only.
The information is preserved in comments at the top of the file.
Note that for non-modular code, MODULE_DEVICE_TABLE is a no-op and
builtin_platform_driver() uses the same init level priority as
module_platform_driver(), so this doesn't change init ordering.
Explicitly disallow driver unbind, since that doesn't have a sensible use
case anyway, and it allows us to drop the ".remove" code for non-modular
drivers.

Several DesignWare-based drivers (dra7xx, exynos, imx6, keystone, qcom, and
spear13xx) had similar loops waiting for the link to come up.
Add a generic dw_pcie_wait_for_link() for use by all these drivers so the
waiting is done consistently, e.g., always using usleep_range() rather than
mdelay() and using similar timeouts and retry counts.
Note that this changes the Keystone link training/wait for link strategy,
so we initiate link training, then wait longer for the link to come up
before re-initiating link training.

The PCIe driver reuses the Designware common code for host and MSI
initialization, and also programs the Qualcomm application specific
registers.
