spi: spi-sg2044-nor: Add configurable chip_info
SG2044 and SG2042 have similar SPI-NOR flash controller design,
but have incompatibility which causes existing driver
not working on SG2042:
1. SPI-NOR flash controller on SG2042 have no OPT register.
2. FIFO trigger level on SG2042 should be strictly less than 8.
So introduce a new configurable chip_info structure to hold the
different configuration.
