fbdev: sh_mobile_lcdc: Compute clock pattern using divider denominator
The clock divider pattern is computed based on the dot clock register value which stores the divider denumerator. However, when using a 1:1 divider ratio, the register is programmed with a value that must not be interpreted as a denominator. This results in a shift left operation with a value of 32, which produces undefined behaviour. Compute the clock pattern using the divider denominator, not the dot clock register value.
