In commit ce4afed839 ("target/arm: Implement AArch32 HCR and HCR2")
the HCR_EL2 register has been changed from type NO_RAW (no underlying
state and does not support raw access for state saving/loading) to
type CONST (TCG can assume the value to be constant), removing the
read/write accessors.
We forgot to remove the previous type ARM_CP_NO_RAW. This is not
really a problem since the field is overwritten. However it makes
code review confuse, so remove it.
