drm/stm: ltdc: add devm_reset_control & platform_get_ressource
Use devm_reset_control_get_exclusive to avoid resource leakage (based
on patch "Convert drivers to explicit reset API" from Philipp Zabel).
Also use platform_get_resource, which is more usual and
consistent with platform_get_irq called later.
