target/adi_v5_swd: update cached value on write to DP_SELECT



When the register DP_SELECT is written directly, e.g. with command
	<dap> dpreg 8 <value>
the cached value in OpenOCD is not completely updated with the new
value, thus creating issues in the following AP and DP read/write
that rely on the cached value.

Update the cached value while writing to DP_SELECT.
