ALSA: hda/realtek: More robust component matching for CS35L41

As the previous commit implies, a system may have a different SPI bus
number that is embedded in the device string.  And, assuming the fixed
bus number is rather fragile; it may be assigned differently depending
on the configuration or on the boot environment.  Once when a bus
number change happens, the binding fails, resulting in the silence.

This patch tries to make the matching a bit more relaxed, allowing to
bind with a different bus number (or without it).  So the previous
fix, the introduction of ALC245_FIXUP_CS35L41_SPI1_2 fixup became
superfluous, and this is unified to ALC245_FIXUP_CS35L41_SPI_2.

Fixes: 225f6e1bc1 ("ALSA: hda/realtek: Add quirk for HP Zbook Firefly 14 G9 model")
