SM502 has a programmable PLL which can provide the panel pixel clock instead
of the 288MHz and 336MHz PLLs.

This patch makes it possible to control panel pins usage with flags passed
from the platform data. Without this patch the sm501fb driver always controls
the VBIASEN and FPEN pins. The polarity and use of these pins are very
platform specific, so this patch introduces the flags
SM501FB_FLAG_PANEL_USE_VBIASEN and SM501FB_FLAG_PANEL_USE_FPEN which enable
the use of these pins.
This patch is needed to support the a Sharp LQ104V1DG21 lcd panel on SuperH
platforms such as R2D-1 and R2D-PLUS boards. Letting the sm501fb driver
control the FPEN and VBIASEN pins like today just results in lcd panel
flicker.

This driver provides the core functionality of the SM501, which is a
multi-function chip including two framebuffers, video acceleration, USB,
and many other peripheral blocks.
The driver exports a number of entries for the peripheral drivers to use.
