[PATCH v2] Staging: fbtft: Fix Sparse warnings

[Frederic Jacob <frederic.jacob.78@gmail.com>]

This fixes the folowing sparse warnings:

fb_hx8340bn.c:111:6: warning: symbol 'set_addr_win' was not declared. Should it be static?
fbtft_device.c:32:19: warning: symbol 'spi_device' was not declared. Should it be static?
fbtft_device.c:33:24: warning: symbol 'p_device' was not declared. Should it be static?

Corrected the changelog to specify the fixed Sparse warnings.
