Adding demo for 32L152CDISCOVERY.

This board contains a STM32L152RCT6 (256 KB Flash, 32 KB RAM).

This commit contains pretty much a copy, paste, replace of the
following:
    ./demos/ARMCM3-STM32L152-DISCOVERY
    ./boards/ST_STM32L_DISCOVERY
    ./os/ports/GCC/ARMCMx/STM32L1xx/ld/STM32L152xB.ld

IDE files have not been copied (.cproject, .project, iar, keil)
as while its likely a simple find and replace I wouldn't have been able to
test them.
