[PATCH for 3.8+] drivers/video/ep93xx-fb.c: fix missing declaration of devm_ioremap()

This fixes the following compile error:
drivers/video/ep93xx-fb.c: In function 'ep93xxfb_probe':
drivers/video/ep93xx-fb.c:532:2: error: implicit declaration of function 'devm_ioremap' [-Werror=implicit-function-declaration]
drivers/video/ep93xx-fb.c:532:17: warning: assignment makes pointer from integer without a cast [enabled by default]
