staging: fbtft: Do not use binary constants

Gcc < 4.3 doesn't understand binary constants (0b*):

drivers/staging/fbtft/fbtft-sysfs.c:156:19: error: invalid suffix "b111" on integer constant
drivers/staging/fbtft/fb_hx8340bn.c:159:3: error: invalid suffix "b1111" on integer constant
drivers/staging/fbtft/fb_hx8340bn.c:159:11: error: invalid suffix "b1111" on integer constant
drivers/staging/fbtft/fb_hx8340bn.c:159:19: error: invalid suffix "b11111" on integer constant
drivers/staging/fbtft/fb_hx8340bn.c:159:28: error: invalid suffix "b1111" on integer constant
drivers/staging/fbtft/fb_hx8340bn.c:159:36: error: invalid suffix "b1111" on integer constant
drivers/staging/fbtft/fb_hx8340bn.c:159:44: error: invalid suffix "b1111" on integer constant
drivers/staging/fbtft/fb_hx8340bn.c:159:52: error: invalid suffix "b11111" on integer constant
drivers/staging/fbtft/fb_hx8340bn.c:160:3: error: invalid suffix "b111" on integer constant
...

Hence use hexadecimal constants (0x*) instead.
