[RFC PATCH] ARM: kexec: Assemble relocate code in ARM mode

[Taras Kondratiuk]

In Thumb2 kernel (CONFIG_THUMB2_KERNEL) kexec's relocate code is assembled
in Thumb2 mode, but cpu_v7_reset() jumps to this code in ARM state,
because its address is page aligned and has 0 in LSB.

Assemble this code in ARM mode to fix the issue.
