[PATCH 2/4] clock-imx35: fix divider if ahb is source for ipg_per

[Michael Grzeschik]

According to the Datasheet:
"i.MX35 (MCIMX35) Multimedia Applications Processor Reference Manual,
Rev. 2" "Table 14-6. PDR0 Field Descriptions" the divider is
CCM_PER_AHB[3:0] + 1.

This patch adds the missing + 1.
