[PATCH v2] staging: gasket: Fix sparse "incorrect type in assignment" warnings.

[Laurence Rochfort]

Correct the coherent buffer data type and memory space cookie.

sparse errors were being generated when passing virt_base to
dma_alloc_coherent().

warning: incorrect type in assignment (different address spaces)
   expected unsigned char [noderef] [usertype] <asn:2>*virt_base
   got void *[assigned] mem
warning: incorrect type in argument 3 (different address spaces)
   expected void *cpu_addr
   got unsigned char [noderef] [usertype] <asn:2>*virt_base

Changes in v2:
- Correct data type rather than forcing type coersion, as per gkh
