Mulin Chao b1214ead19 driver: i2c: npcx: simplify smb bank registers with union 
For NPCX SMB/I2C SMB modules in FIFO mode, the registers include:

* Common registers, offset 0x00-0x0f, accessible regardless of the value
  of BNK_SEL
* Bank 0 registers, offset 0x10-0x1e, accessible if BNK_SEL is set to 0
* Bank 1 registers, offset 0x10-0x1e, accessible if BNK_SEL
is set to 1

In the current driver, it uses two structures, `smb_reg` and
`smb_fifo_reg`, to access `Common + Bank 0` and `Common + Bank 1`
registers. But It might be easy to misunderstand that they are two
different modules.

This CL tries to simplify this by the following steps:

1. Use `union` to combine `Bank 0/1` registers in the same structure.
2. Remove `smb_fifo_reg`. We needn't use two structures to present
   SMB registers.
