mtk_spi_config() and mtk_spi_prepare_message() both initialize
spi register, so remove mtk_spi_config() and init all register

Mediatek spi HW can't set cs inactive(keep cs high) directly.
Instead, it supplies pause mode to do it indirectly. If driver
unsets SPI_CMD_PAUSE_MODE in CMD_REG, it also needs to reset
internal state machine to let cs inactive at once.
