mtk-mmc: replace empty body macros

Replace macros with empty body with 'do {} while (0)'.
Remove unnecessary semicolons.

Fixes:
drivers/mmc/host/mtk-mmc/sd.c: In function 'msdc_irq':
drivers/mmc/host/mtk-mmc/sd.c:1969:87: error: suggest braces around empty body in an 'else' statement [-Werror=empty-body]
