[PATCH] spi: Mediatek: fix endian warnings

[Leilk Liu <leilk.liu@mediatek.com>]

This patch fixes endian warnings detected by sparse:
- sparse: incorrect type in argument 1 (different base types)
	  expected unsigned int [unsigned] val
	  got restricted __le32 [usertype] <noident>
- sparse: incorrect type in argument 1 (different base types)
	  expected unsigned int [unsigned] val
	  got restricted __le32 [usertype] <noident>
