This patch changes clock for FIMD from 'fimd' to 'lcd'.
Also, devname for FIMD is changed from 's5pv310-fb' to 'exynos4-fb'.

As I remember, some guys discussed about the clock name before.
Please refer to the following diagram. Before EXYNOS4210 clk 'lcd' was used
for FIMD IP core clock and source of the LCD pixel clock. But the mux used
to select source of LCD pixel clock is removed. So 'lcd' clock is only used
for core clock of FIMD IP. It isn't used for LCD pixel clock.
As a result clock name was changed from lcd to fimd in the EXYNOS4210
datasheet.
In drivers/video/s3c-fb.c:s3c_fb_probe(), the bus clock is assumed to be
'lcd'. The bus clock name in all other related machine folder is 'lcd'.
Hence for consistency, we might consider renaming 'fimd'==>'lcd', even
though the clock name is different in the datasheet.
