[PATCH 02/10] staging: ks7010: use u8 instead of unsigned char in write_to_device function

[Sergio Paracuellos]

Parameter buffer in write_to_device function is declared as
a pointer to unsigned char and can be declared as an u8 type
which is preferred. Internally it calls to ks7010_sdio_write
which is using also u8 as parameter type. Update calls to this
function as well.
