mcp16502_suspend/resume_noirq is only used by SET_NOIRQ_SYSTEM_SLEEP_PM_OPS
when CONFIG_PM_SLEEP is defined.
So use #ifdef CONFIG_PM_SLEEP instead CONFIG_SUSPEND guard.

This patch does the following:
- align parameter with parenthesis
- fix compile error
If CONFIG_SUSPEND is not set the dummy pm_ops
callbacks are named mcp16502_suspend and mcp16502_resume
instead of mcp16502_suspend_noirq and mcp16502_resume_noirq.

This patch adds support for entering/resuming suspend states.
It does this by setting the LPM pin of the PMIC.
When suspending the PMIC will enter the Low-power mode
when the LPM pin will be set to high. If the suspend target state
is suspend-to-mem, the PMIC will transition to Hibernate mode,
otherwise, if it is standby, it will remain in Low-power mode.

This patch adds a regulator driver for the MCP16502 PMIC.
This drivers supports basic operations through the
regulator interface such as:
- setting/reading voltage
- setting/reading operating mode
- reading current status
