The GPIO support is needed in SPL to managed the SD cart detect
used on stm32mp157c-ev1 and dk2 board.
So this patch activates the associated code in stm32_gpio.c.

At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.
Move the compatibility features into a separate header file.

As compatible string "st,stm32-gpio" is no more used, .ofmatch
callback becomes useless, remove it.

As this driver is used on stm32f4/f7/h7 and stm32mp1
SoCs, rename it with a more generic name.

Use available DM stm32f7_gpio.c and pinctrl_stm32.c drivers
instead of board GPIO initialization.
Remove stm32_gpio.c which is no more used and migrate
structs stm32_gpio_regs and stm32_gpio_priv into
arch-stm32f4/gpio.h to not break compilation.

A few years ago STM32F1 SoCs support has been added :
0144caf22ce6acd5c gpio: stm32: add stm32f1 support
2d18ef2364fd3561a ARMv7M: add STM32F1 support
But neither STM32F1 dedicated defconfig nor board was
associated to these commits.
Got confirmation from Tom Rini and Matt Porter to remove
all this code [1]

Now, arch/${ARCH}/include/asm/errno.h and include/linux/errno.h have
the same content. (both just wrap <asm-generic/errno.h>)
Replace all include directives for <asm/errno.h> with <linux/errno.h>.
