regulator: Add helpers for low-level register access

Add helper functions that allow regulator consumers to obtain low-level
details about the regulator hardware, like the voltage selector register
address and such. These details can be useful when configuring hardware
or firmware that want to do low-level access to regulators, with no
involvement from the kernel.

The use-case for Tegra is a voltage-controlled oscillator clocksource
which has control logic to change the supply voltage via I2C to achieve
a desired output clock rate.

regulator: add regulator_can_change_voltage stub

When CONFIG_REGULATOR is not set, we cannot call
regulator_can_change_voltage() from a device driver, which results
in a build error like

video/fbdev/omap2/dss/hdmi5.c: In function 'hdmi_init_regulator':
video/fbdev/omap2/dss/hdmi5.c:149:2: error: implicit declaration of function 'regulator_can_change_voltage' [-Werror=implicit-function-declaration]

even for drivers that don't require the regulator API normally.
Such a use was recently added in the omap2+ hdmi driver.

This avoids the problem by adding a static inline function
stub in the API header, as we have for most of the other
regulator functions as well.

We already have dummy implementation for most of the regulators APIs for
!CONFIG_REGULATOR case and were missing it for regulator_set_voltage_time().

Found this issue while compiling cpufreq-cpu0 driver without regulators support
in kernel.

drivers/cpufreq/cpufreq-cpu0.c: In function ‘cpu0_cpufreq_probe’:
drivers/cpufreq/cpufreq-cpu0.c:186:3: error: implicit declaration of function ‘regulator_set_voltage_time’ [-Werror=implicit-function-declaration]

Fix this by adding dummy definition for regulator_set_voltage_time().

regulator: core: Return error in get optional stub

Drivers that call regulator_get_optional are tolerant to the absence of
that regulator.  By modifying the value returned from the stub function
to match that seen when a regulator isn't present, callers can wrap the
regulator logic with an IS_ERR based conditional even if they happen to
call regulator_is_supported_voltage.  This improves efficiency as well
as eliminates the possibility for a very subtle bug.
