Add uppercase macro to build_macros.mk 

This patch adds `uppercase` macro to prepare IMAGE_BLxx defines
used for conditional compilation and to prepare variables used
for defining BL source and linker file names.

This change is needed for upcoming BL images that can have names
which uses both letters and numbers.
