Subject: [PATCH 1/1] staging: fbtft: Fix Sparse warning in fb_watterott.c

Sparse reports the following in fb_watterott.c:

warning: incorrect type in assignment (different base types)
expected unsigned short [unsigned] [short] [usertype] <noident>
got restricted __be16 [usertype] <noident>

Use __be16 types for endian correctness
