MCDE: Supports new HDMI features
This patch does the following: * Dynamic resolution change (HDMI and TV-out) * Dynamic change of rotation (Main display) * Dynamic change to 24 and 32 bpp (RGB888, RGBA8888, RGBX8888) * HDMI stability improvements * Removes Framebuffer_console for V.20 and HREF+. * Support for disabling display initialization if u-boot supports startup graphics * Adds prcmu handling from the mcde driver ST Ericsson Change-Id: WP259361 Signed-off-by: Mian Yousaf Kaukab <mian.yousaf.kaukab@stericsson.com> Change-Id: I37e91d49f1550a3ecd041d4ddf67ce57e086772c Reviewed-on: http://gerrit.lud.stericsson.com/gerrit/2536 Reviewed-by: Jonas ABERG <jonas.aberg@stericsson.com>
