>From the specification SCTLR_EL2.TSCXT is RES1 only "When
FEAT_CSV2_2 is not implemented, FEAT_CSV2_1p2 is not
implemented, HCR_EL2.E2H == 1 and HCR_EL2.TGE == 1", so
given that HCR_EL2.E2H is set by bootwrapper before to a
value of zero, the condition above can't happen and from
the specification the bit is RES0.
Fix the macro removing the bit.
