[PATCH v2 2/3] staging: fbtft: Replace magic number with constant

["Tobin C. Harding" <me@tobin.cc>]

Current call to strncmp() uses a magic number. There is a compile
time constant defined for this buffer, included and used already at
other sites in the file.

Remove magic number. Replace with pre-existing compile time constant.
