arm64: Always use individual bits in CPACR floating point enables

Browse source

CPACR_EL1 has several bitfields for controlling traps for floating point
features to EL1, each of which has a separate bits for EL0 and EL1. Marc
Zyngier noted that we are not consistent in our use of defines to
manipulate these, sometimes using a define covering the whole field and
sometimes using defines for the individual bits. Make this consistent by
expanding the whole field defines where they are used (currently only in
the KVM code) and deleting them so that no further uses can be
introduced.
