arm64: fpsimd: Fold sve_init_regs() into do_sve_acc()

Browse source

For historical reasons, do_sve_acc() is structurally different from
do_sme_acc(), and the logic to convert the task from FPSIMD to SVE is
out-of-line in sve_init_regs(). We only use sve_init_regs() within
do_sve_acc(), so it's not necessary for this to be a separate function.

Fold sve_init_regs() into do_sve_acc(), and simplify the associated
comments. This makes do_sve_acc() structurally similar to do_sme_acc(),
making it easier to see similarities and differences.

There should be no functional change as a result of this patch.
