Subject: [PATCH v2 1/2] arch: Add asm-generic/initrd.h and make use of it for most architectures

In preparation for separating the definition of
__early_init_dt_declare_initrd() on ARM64 in order to cut the amount of
files that require a rebuild when CONFIG_BLK_DEV_INITRD value is
changed, introduce an empty asm-generic initrd.h file and update all
architectures but arm64 to make use of it.
