of/flattree: use callback to setup initrd from /chosen
At present, the fdt code sets the kernel-wide initrd_start and
initrd_end variables when parsing /chosen. On ARM, we only set these
once the bootmem has been reserved.
This change adds an arch hook to setup the initrd from the device
tree:
void early_init_dt_setup_initrd_arch(unsigned long start,
unsigned long end);
The arch-specific code can then setup the initrd however it likes.
Compiled on powerpc, with CONFIG_BLK_DEV_INITRD=y and =n.
