spi25_statusreg: Allow WRSR_EXT for Status Register 3

Browse Source 
Spansion flash chips S25FL128L and S25FL256L use the WRSR instruction to
write more than 2 registers. So align SR2 and SR3 support: The current
FEATURE_WRSR_EXT is renamed to FEATURE_WRSR_EXT2 and FEATURE_WRSR_EXT3
is added. Also, WRSR3 needs a separate flag now.

Verified that FEATURE_WRSR_EXT2 still works using the `dummy_flasher`.
