[PATCH v11 2/8] RISC-V: Rename relocate() and make it global

From: Anup Patel <anup.patel at wdc.com>

The low-level relocate() function enables mmu and relocates
execution to link-time addresses. We rename relocate() function
to relocate_enable_mmu() function which is more informative.

Also, the relocate_enable_mmu() function will be used in the
resume path when a CPU wakes-up from a non-retentive suspend
so we make it global symbol.
