The call to spi_master_put() in mtk_spi_remove() is redundant since
the master is registered using devm_spi_register_master() and no
reference hold by using spi_master_get() in mtk_spi_remove().This is detected by Coccinelle semantic patch.

In the case where transfer length is not a multiple of 4, KASAN
reports 2 out-of-bounds memory accesses:
- mtk_spi_interrupt: ioread32_rep writes past the end of
trans->rx_buf.
- mtk_spi_fifo_transfer: iowrite32_rep reads past the end of
xfer->tx_buf.Fix this by using memcpy on the remainder of the bytes.

When only one device is present, it is not necessary to specify
cs_gpios, as the CS line can be controlled by the hardware
module.Without this patch, older device tree bindings used before
37457607 "spi: mediatek: mt8173 spi multiple devices support"
would cause a panic on boot. This fixes the crash, and
re-introduces backward compatibility.Signed-off-by: Nicolas Boichat

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.Signed-off-by: Leilk Liu

spi clock manages flow:
CLK_TOP_SYSPLL3_D2 ---> CLK_TOP_SPI_SEL ---> CLK_PERI_SPI0
(source clock) (clock mux) (clock gate)
spi driver should choose source clock by clock mux, then enable
clock gate.Signed-off-by: Leilk Liu
