[ARM] pxafb: allow better platform configurable smart panel timing
For smart panels (LCD panel with internal framebuffer), the following
LCCR3 register bits have different meanings than the parallel one:
LCCR3_PCP - controls the L_PCLK_WR polarity
LCCR3_HSP - controls the L_LCLK_A0 polarity
LCCR3_VSP - controls the L_FCLK_RD polarity
To keep minimum change to the original parallel timing, the .lcd_conn
flags and 'pxafb_mode_info.sync' are re-used to reflect this:
LCD_PCLK_EDGE_{RISE,FALL} - configures LCCR3_PCP
sync & FB_SYNC_{HOR,VERT}_HIGH_ACT - configures LCCR3_{HSP,VSP}
