[PATCH] spi: mediatek: Use of_device_get_match_data()

[Ryder Lee]

The usage of of_device_get_match_data() reduce the code size a bit.

Also, the only way to call mtk_spi_probe() is to match an entry in
mtk_spi_of_match[], so of_id cannot be NULL.

Hi Mark,

Is it okay with you?

Please don't send content free pings and please allow a reasonable time
for review.  People get busy, go on holiday, attend conferences and so 
on so unless there is some reason for urgency (like critical bug fixes)
please allow at least a couple of weeks for review.  If there have been
review comments then people may be waiting for those to be addressed.
Sending content free pings just adds to the mail volume (if they are
seen at all) and if something has gone wrong you'll have to resend the
patches anyway.
