[U-Boot] [PATCH v3] Remove static type from gunzip_bmp()

[Mark Jackson <mpfj@mimc.co.uk>]

The current bmp routines support gzipped files, but compilation fails (under
AVR32) due to the gunzip_bmp() function being defined as static.

This patch fixes this problem.

The gunzip_bmp routine has also now been defined in the lcd.h header file.
