MLK-16787-1 HAB: Update hab codes to support ARM64 and i.MX8M
There are some changes to support ARM64 i.MX8M platform in this patches:
1. The hab_rvt base and function vectors are different as i.MX6/7
2. Need to bypass an workaround for i.MX6 to fix problem in MMU.
3. The x18 register needed save & restore before calling any HAB API. According
to ARM procedure call spec, the x18 is caller saved when it is used as
temporary register. So calling HAB API may scratch this register, and
cause crash once accessing the gd pointer.
On ARMv7, the r9 is callee saved when it is used as variable register. So
no need to save & restore it.
