Support command queue for mt6779 platform.
a. Add msdc_set_busy_timeout() to calculate emmc write timeout.
b. Connect mtk msdc driver to cqhci driver through
host->cq_host->ops = &msdc_cmdq_ops;
c. msdc_cmdq_irq() will link up with cqchi_irq(). Besides, it provides
more irq error messages like RSPCRCERR/CMDTO/DATACRCERR/DATTMO.
d. Select kernel config MMC_CQHCI for MMC_MTK

Drivers using legacy PM have to manage PCI states and device's PM states
themselves. They also need to take care of configuration registers.
With improved and powerful support of generic PM, PCI Core takes care of
above mentioned, device-independent, jobs.
This driver makes use of PCI helper functions like
pci_save/restore_state(), pci_enable/disable_device(),
pci_enable_wake() and pci_set_power_state() and to do required operations.
In generic mode, they are no longer needed.
Change function parameter in both .suspend() and .resume() to
"struct device*" type. Use dev_get_drvdata() to get drv data.
Compile-tested only.

As commit ef6b75671b5f ("mmc: sdhci-cadence: send tune request twice to
work around errata") stated, this IP has an errata. This commit applies
the second workaround for the SD mode.
Due to the errata, it is not possible to use the hardware tuning provided
by SDHCI_HOST_CONTROL2.
Use the software-controlled tuning like the eMMC mode.
Set sdhci_host_ops::platform_execute_tuning instead of overriding
mmc_host_ops::execute_tuning.

The initial code that was adding delays was doing a cast over undefined
memory. This meant that the delays would be all gibberish.
This change, allocates all delays on the stack, and assigns them from the
ZynqMP & Versal macros/phase-list. And then finally copies them over the
common iclk_phase & oclk_phase variables.

Using uninitialized_var() is dangerous as it papers over real bugs[1]
(or can in the future), and suppresses unrelated compiler warnings
(e.g. "unused variable"). If the compiler thinks it is uninitialized,
either simply initialize the variable or make compiler changes.
In preparation for removing[2] the[3] macro[4], remove all remaining
needless uses with the following script:
git grep '\buninitialized_var\b' | cut -d: -f1 | sort -u | \
xargs perl -pi -e \
's/\buninitialized_var\(([^\)]+)\)/\1/g;
s:\s*/\* (GCC be quiet|to make compiler happy) \*/$::g;'
drivers/video/fbdev/riva/riva_hw.c was manually tweaked to avoid
pathological white-space.
No outstanding warnings were found building allmodconfig with GCC 9.3.0
for x86_64, i386, arm64, arm, powerpc, powerpc64le, s390x, mips, sparc64,
alpha, and m68k.

On qcom SD host controllers voltage switching be done after the HW
is ready for it. The HW informs its readiness through power irq.
The voltage switching should happen only then.
Use the internal voltage switching and then control the voltage
switching using power irq.
IO-bus supply of eMMC would be kept always-on. So set the load
for this supply to configure it in LPM when eMMC is suspend state
and in HPM when eMMC is active.
