ARM: OMAP2+: Remove unnecesssary GPMC definitions and variable
With commit 21cc2bd (ARM: OMAP2+: Remove apollon board support) the variable "boot_rom_space" is now not needed and the code surrounding this variable can be cleaned up and simplified. Remove unnecessary definitions and clean-up the comment as well. Signed-off-by: Jon Hunter <jon-hunter@ti.com> Tested-by: Ezequiel Garcia <ezequiel.garcia@free-electrons.com>
