ARM: imx: cpuidle-imx6sx: Restrict the SW2ISO increase to i.MX6SX
Since commit 1e434b703248 ("ARM: imx: update the cpu power up timing
setting on i.mx6sx") some characters loss is noticed on i.MX6ULL UART
as reported by Christoph Niedermaier.
The intention of such commit was to increase the SW2ISO field for i.MX6SX
only, but since cpuidle-imx6sx is also used on i.MX6UL/i.MX6ULL this caused
unintended side effects on other SoCs.
Fix this problem by keeping the original SW2ISO value for i.MX6UL/i.MX6ULL
and only increase SW2ISO in the i.MX6SX case.
