The RZ/G2L VSPD provides a single VSPD instance. It has the following
sub modules MAU, CTU, RPF, DPR, LUT, BRS, WPF and LIF.

The VSPD block on RZ/G2L does not have a version register, so added a
new compatible string "renesas,rzg2l-vsp2" with a data pointer containing
the info structure. Also the reset line is shared with the DU module.

v3->v4:
 * Restored error check for pm_runtime_resume_and_get and calls
   assert() in case of failure.
 * Added Rb tag from Geert
 * Add switch() for LIF0 buffer attribute handling for RZ/G2L and V3M SoC's
v2->v3:
 * Added Rb tags from Krzysztof and Philipp
 * If reset_control_deassert() failed, return ret directly.
 * Fixed version comparison in vsp1_lookup()
v1->v2:
 * Used reference counted reset handle to perform deassert/assert
 * Changed the compatible from vsp2-rzg2l->rzg2l-vsp2
 * Added standalone device info for rzg2l-vsp2.
 * Added vsp1_lookup helper function.
 * Updated comments for LIF0 buffer attribute register
 * Used last ID for rzg2l-vsp2.
RFC->v1:
 * Added reset support as separate patch
 * Moved rstc just after the bus_master field in struct vsp1_device
 * Used data pointer containing info structure to retrieve version information
 * Updated commit description
 * Changed compatible from vsp2-r9a07g044->vsp2-rzg2l
 * Defined the clocks
 * Clock max Items is based on SoC Compatible string
