cfi_flash: Fix devicetree address determination
The cfi-flash driver uses an open-coded version of the generic
algorithm to decode and translate multiple frames of a "reg" property.
This starts off the wrong foot by using the address-cells and size-cells
properties of *this* very node, and not of the parent. This somewhat
happened to work back when we were using a wrong default size of 2,
but broke about a year ago with commit
0ba41ce1b781 ("libfdt: return
correct value if #size-cells property is not present").
Instead of fixing the reinvented wheel, just use the generic function
that does all of this properly.
This fixes U-Boot on QEMU (-arm64), which was crashing due to decoding
a wrong flash base address:

pwm: Add driver for Amlogic Meson PWM controller
This adds the driver for the PWM controller found in the Amlogic SoCs.
This PWM is only a set of Gates, Dividers and Counters:
PWM output is achieved by calculating a clock that permits calculating
two periods (low and high). The counter then has to be set to switch after
N cycles for the first half period.
The hardware has no "polarity" setting. This driver reverses the period
cycles (the low length is inverted with the high length) for
PWM_POLARITY_INVERSED.

gpio: stm32: check result of ofnode_phandle_args
Add test on the size of ofnode_phandle_args result to avoid access
to uninitialized elements in args[] field.
This patch avoids the issue when gpio-ranges cell size is not 3 as
expected, for example:
gpio-ranges = <&pinctrl 0>;
instead of
gpio-ranges = <&pinctrl 0 112 16>;
