[PATCH] staging: fbtft: Fix type mismatch found with sparse

[Thomas Gardner]

The warning below is resolved by changing the LHS cast to __be64.

fbtft/fbtft-io.c:74:29: warning: incorrect type in assignment (different base types)
fbtft/fbtft-io.c:74:29:    expected unsigned long long [unsigned] [long] [long long] [usertype] <noident>
fbtft/fbtft-io.c:74:29:    got restricted __be64 [usertype] <noident>
