aarch64: Fix pmsdsfr_el1 encoding

The encoding was fixed in Binutils in May 2024, but we didn't copy the
fix to GCC at the time.

gcc/ChangeLog:

	* config/aarch64/aarch64-sys-regs.def: Fix pmsdsfr_el1 encoding.

gcc/testsuite/ChangeLog:

	* gcc.target/aarch64/acle/rwsr-armv8p9.c: Fix pmsdsfr_el1
	encoding.
