writeprotect.c: refactor and fix wp_mode functions

This is a follow up on commit 12dbc4e04508aecfff53ad95b6f68865da1b4f07.

Use a lookup table in get_wp_mode() and drop the srp_bit_present check,
since a chip without SRP is just FLASHROM_WP_MODE_DISABLED.

Add a srp_bit_present check to set_wp_mode() if the mode requires it.

Tested: flashrom --wp-{enable,disable,status} on AMD dut
