Register X0 contains PIE_E1_ASM and should not be written into REG_TCR2_EL1
which could have an adverse impact otherwise. This has remained undetected
till now probably because current value for PIE_E1_ASM (0xcc880e0ac0800000)
clears TCR2_EL1 which again gets set subsequently with 'tcr2' after testing
for FEAT_TCR2.
Drop this unwarranted 'msr' which is a stray change from an earlier commit.
This line got re-introduced when rebasing on top of the commit 926b66e2eb
("arm64: setup: name 'tcr2' register").
