[PATCH] remoteproc/mediatek: fix sparse errors

[Tzung-Bi Shih <tzungbi@xxxxxxxxxx>]

Fixes the following sparse errors:

warning: incorrect type in argument 2 (different address spaces)
   expected void volatile [noderef] __iomem *addr
   got void *addr
warning: incorrect type in argument 1 (different address spaces)
   expected void *addr
   got void [noderef] __iomem *
warning: incorrect type in assignment (different address spaces)
   expected void [noderef] __iomem *cpu_addr
   got void *
warning: incorrect type in argument 3 (different address spaces)
   expected void *cpu_addr
   got void [noderef] __iomem *cpu_addr
