[U-Boot] [PATCH v3 2/2] armv7m: Fix larger builds

[Phil Edworthy]

The branch instruction only has an 11-bit relative target address, which
is sometimes not enough.

v3:
 - Move CONFIG_ARM_ASM_UNIFIED and CONFIG_THUMB2_KERNEL to Kconfig
v2:
 - Use W(b) instead of ldr+mov. Using this macro requires
   CONFIG_ARM_ASM_UNIFIED and CONFIG_THUMB2_KERNEL to be defined.
