ArmPkg: Configure TTBCR register

Architecturally, the TTBCR register value is undefined at reset for
Non-Secure.
On some platforms the reset value for TTBCR is not zero and
this causes a data abort exception once the MMU is enabled.

This patch configures the TTBCR register to enable translation table
walk using TTBR0.
