The new challenge is to remove VLAs from the kernel
(see https://lkml.org/lkml/2018/3/7/621)
This patch replaces several a VLA with an appropriate call to
kmalloc_array.

UniPhier SoCs have the following pins for hardware flow control of UART:
XRTS, XCTS
and for modem control of UART:
XDTR, XDSR, XDCD, XRI
The port number with the flow control is SoC-dependent.

The Allwinner H6 SoC has two pin controllers, one main controller
(called CPUX-PORT in user manual) and one controller in CPUs power
domain (called CPUS-PORT in user manual).
This commit introduces support for the main pin controller on H6.
The pin bank A and B are not wired out and hidden from the SoC's
documents, however it's shown that the "ATE" (an AC200 chip
co-packaged with the H6 die) is connected to the main SoC die via these
pin banks. The information about these banks is just copied from the BSP
pinctrl driver, but re-formatted to fit the mainline pinctrl driver
format. The GPIO functions are dropped, as they're impossible to use --
except a GPIO&IRQ only pin (PB20) which might be the IRQ of ATE.

The Allwinner H6 SoC have its pin controllers with the first IRQ-capable
GPIO bank at IRQ bank 1 and the second bank at IRQ bank 5.
Change the current code that uses IRQ bank base to a IRQ bank map, in
order to support the case that holes exist among IRQ banks.

The Allwinner H6 SoC have its pin controllers with the first IRQ-capable
GPIO bank at IRQ bank 1 and the second bank at IRQ bank 5. Some
refactors in the sunxi pinctrl framework are needed.
This commit introduces a IRQ bank conversion function, which replaces
the "(bank_base + bank)" code in IRQ register access.

The brcms_ucode_init_buf() duplicates the ucode chunks via kmemdup()
with GFP_ATOMIC as a precondition of wl->lock acquired. This caused
allocation failures sometimes as reported in the bugzilla below.
When looking at the the real usage, one can find that it's called
solely from brcms_request_fw(), and it's obviously outside the lock.
Hence we can use GFP_KERNEL there safely for avoiding such allocation
errors.

stm32mp1 RCC IP 1 has a reset SET register and a reset CLEAR register.
Writing '0' on reset SET register has no effect
Writing '1' on reset SET register
activates the reset of the corresponding peripheral
Writing '0' on reset CLEAR register has no effect
Writing '1' on reset CLEAR register
releases the reset of the corresponding peripheral
