These bits (MDCR_EL3.{NSTB, NSTBE, TTRF, TPM}, CPTR_EL3.TTA) only affect
EL2 (and lower) execution. Each feat_init_el3() is called long before
any lower EL has had a chance to execute, so setting the bits at reset
is redundant. Removing them from reset code also improves readability of
the immutable EL3 state.
Preserve the original intention for the TTA bit of "enabled for NS and
disabled everywhere else" (inferred from commit messages d4582d3088 and
2031d6166a and the comment). This is because CPTR_EL3 will be contexted
and so everyone will eventually get whatever NS has anyway.
