store lcd clk rate always, i.e. irrespective of whether CPUFREQ is
enabled or not. This can be used to get clk rate directly instead of
enquiring with clock framework with clk handle every time.

The naming related to this clock is quite confusing. There's
lcd_fck_rate, fb_clk and lcdc_clk, all of which refer to the same clock
as far as I understand.
