spi: Add Amlogic SPISG driver
Introduced support for the new SPI IP (SPISG) driver. The SPISG is
a communication-oriented SPI controller from Amlogic,supporting
three operation modes: PIO, block DMA, and scatter-gather DMA.
Due to there is no FIFO, PIO mode can only transfer one word at
a time, which is extremely slow. Therefore, this mode was not
implemented.
