atmel_lcdfb: new alternate pixel clock formula
atmel_lcdfb: new alternate pixel clock formula

at91sam9g45 non ES lots have an alternate pixel clock calculation formula.
Introduce this one with condition on the cpu_is_xxxxx() macros.

Newer 9g45 SOC will not have good pixel clock calculation without this
fix.
