[U-Boot] [PATCH 10/29] blackfin: Avoiding using P3 in early init

[Simon Glass]

The P3 register is used to hold the global_data pointer. At present this
is not set up until cpu_init_f() is called, but we want to instead set it
up using the standard board_init_f_init_reserve() function. To avoid it
being overwritten use P2 instead of P3 in early init.
