lcd: JZ4750: Start separating panel init from fb init
lcd: JZ4750: Remove uselless slcd_init(), data is set later anyway
lcd: JZ4750: Split panel init from gpio_init() and panel enable from ctrl_enable
lcd: JZ4750: Store jzfb pointer into drvdata
lcd: JZ4750: Implement blank (disabled for slcd for now)
lcd: a380: JZ4750: Turn some macros into funstions
lcd: JZ4750: Turn macros into functions for all panels
lcd: JZ4750: Merge jz4750fb_set_mode() into jz4750fb_deep_set_mode()
lcd: JZ4750: Inline function jz4750fb_free_fb_info()
lcd: JZ4750: Drop support for paletted modes (bpp <= 8, 15)

Reason:
  Modes with bpp <= 8 are supported by FG0 only for LCD output.
  TV encoder demands 16/32 bpp for FG0/FG1,
  IPU use 16/32 bpp and FG1 only.
lcd: JZ4750: Fix compilation warnings
lcd: JZ4750: Completely remove osd structs

Though lcd is still working in OSD mode with fg0.
