clk: qcom: gcc-sc7180: Add 50 MHz clock rate for SDC2

50 MHz is an incredibly common clock rate for SD cards to run at.
It's "high speed" mode in SD (not very fast these days, but it used to
be) or:
  #define HIGH_SPEED_MAX_DTR 50000000

If we don't support this then older "high speed" cards can only run at
25 MHz or at half their normal speed.  There doesn't seem to be any
reason to skip this clock rate, so add it.

clk: samsung: Prevent potential endless loop in the PLL ops

The PLL status polling loops in the set_rate callbacks of some PLLs
have no timeout detection and may become endless loops when something
goes wrong with the PLL.

For some PLLs there is already the ktime API based timeout detection,
but it will not work in all conditions when .set_rate gets called.
In particular, before the clocksource is initialized or when the
timekeeping is suspended.

This patch adds a common helper with the PLL status bit polling and
timeout detection. For conditions where the timekeeping API should not
be used a simple readl_relaxed/cpu_relax() busy loop is added with the
iterations limit derived from measurements of readl_relaxed() execution
time for various PLL types and Exynos SoCs variants.

Actual PLL lock time depends on the P divider value, the VCO frequency
and a constant PLL type specific LOCK_FACTOR and can be calculated as

 lock_time = Pdiv * LOCK_FACTOR / VCO_freq

For the ktime API use cases a common timeout value of 20 ms is applied
for all the PLLs with an assumption that maximum possible value of Pdiv
is 64, maximum possible LOCK_FACTOR value is 3000 and minimum VCO
frequency is 24 MHz.

Commit 21653a4181ff ("i2c: core: Call i2c_acpi_install_space_handler()

the ACPI declared i2c-children of the adapter where instantiated by
i2c_acpi_register_devices().

But i2c_acpi_install_space_handler() had a call to
acpi_walk_dep_device_list() hidden (that is I missed it) at the end
of it, so as an unwanted side-effect now acpi_walk_dep_device_list()
was also being called before i2c_acpi_register_devices().

Move the acpi_walk_dep_device_list() call to the end of
i2c_acpi_register_devices(), so that it is once again called *after*
the i2c_client-s hanging of the adapter have been created.

This fixes the Microsoft Surface Go 2 hanging at boot.
