target-arm: Fix reset and migration of TTBCR(S)
Commit 6459b94c26dd666badb3 broke reset and migration of the AArch32 TTBCR(S) register if the guest used non-LPAE page tables. This is because the AArch32 TTBCR register definition is marked as ARM_CP_ALIAS, meaning that the AArch64 variant has to handle migration and reset. Although AArch64 TCR_EL3 doesn't need to care about the mask and base_mask fields, AArch32 may do so, and so we must use the special TTBCR reset and raw write functions to ensure they are set correctly. This doesn't affect TCR_EL2, because the AArch32 equivalent of that is HTCR, which never uses the non-LPAE page table variant.
