sh_mobile_meram: MERAM framework for LCDC
Based on the patch by Takanari Hayama <taki@igel.co.jp>
Adds support framework necessary to use Media RAM (MERAM)
caching functionality with the LCDC. The MERAM is accessed
through up to 4 Interconnect Buffers (ICBs).
ICB numbers and MERAM address ranges to use are specified in
by filling in the .meram_cfg member of the LCDC platform data
