video: tegra20: dsi: use regulator_set_enable_if_allowed

With the commit 4fcba5d ("regulator: implement basic reference counter") the return value of regulator_set_enable may be EALREADY or EBUSY for fixed/gpio regulators and may be further expanded on all regulators. Change to use the more relaxed regulator_set_enable_if_allowed to continue if regulator already was enabled or disabled. Signed-off-by: Svyatoslav Ryhel <[email protected]>
