pik_clock: make divider value check limit as configurable parameter

Darryl Green requested to merge github/fork/manojkumar-arm/pik-clock-divider-fix into master

Created by: manojkumar-arm

PIK clock divider value limit checking is hardcoded to 16 with 4-bit assumption. However many mobile & infra platforms has 5-bit divider.

This patch fixes the issue by adding a configurable module parameter so that the platform's config file can set the divider bitfield size based on platform.

Additionally, if platform does not provide module configuration data, then the divider limit is set to a default value of 5-bits.
