i2c: npcm: Remove own slave addresses 2:10
[ Upstream commit 47d506d1a28fd10a9fb1f33df5622d88fae72095 ]
NPCM can support up to 10 own slave addresses. In practice, only one
address is actually being used. In order to access addresses 2 and above,
need to switch register banks. The switch needs spinlock.
To avoid using spinlock for this useless feature removed support of SA >=
2. Also fix returned slave event enum.
Remove some comment since the bank selection is not required. The bank
selection is not required since the supported slave addresses are reduced.
