[PATCH v3 1/8] arm: gpio: include integer type definitions for gpio.h

[Mathew McBride]

Both consumers and sub-arch specific versions of gpio.h
may reference stdint or other non-C90 type definitions.

Ensure the common ones are available by including linux/types.h
before any other headers.

This issue came to light when the usb onboard hub driver
was enabled for ten64_tfa_defconfig:

In file included from ./arch/arm/include/asm/gpio.h:2,
		 from common/usb_onboard_hub.c:10:
./arch/arm/include/asm/arch/gpio.h:17:9: error: unknown type name 'ulong'
   17 |         ulong addr;
./arch/arm/include/asm/arch/gpio.h:18:9: error: unknown type name 'ulong'
   18 |         ulong size;
./arch/arm/include/asm/arch/gpio.h:19:9: error: unknown type name 'uint'
   19 |         uint ngpios;

(In this instance, the cited errors actually originate from
arch/arm/include/asm/arch-fsl-layerscape/gpio.h, which is included
by the arm top level asm/gpio.h)

Implemented as per suggestion from Quentin Schulz in Link:
