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 SoCs does not have a version register, so
added a new compatible string "renesas,r9a07g044-vsp2" with a data
pointer containing the info structure. Also the reset line is shared
with the DU module.

v9->v10:
* No change.
v8->v9:
* Replaced the code comments RZ/G2L {SoC's,SoC} with RZ/G2L SoCs.
v7->v8:
* Split the patch for adding s/w version, feature bit and RZ/G2L support
* Added feature bit VSP1_HAS_NON_ZERO_LBA to device_info
* Added .soc for RZ/G2L
* Replaced the compatible "renesas,rzg2l-vsp2" -> "renesas,r9a07g044-vsp2"
v6->v7:
* Added Rb tag from Kieran
* Added a quirk to handle LIF0 buffer attribute related
changes for V3M and G2L.
* Removed the macro for VSP HW version
v5->v6:
* Rebased to media_staging and updated commit header
* Removed the extra tab from rzg2l_vsp2_device_info
* Changed the function vsp1_lookup->vsp1_lookup_info and
all info match related code moved here.
* Add VI6_IP_VERSION_VSP and VI6_IP_VERSION_VSP_SW macros to
distinguish HW & SW IP_VSP_Version.
* Used 0x80 for RZG2L VSPD model and SoC identification
* Updated Switch() for LIF0 buffer attribute handling.
v4->v5:
* Fixed typo VI6_IP_VERSION_MODEL_MASK->VI6_IP_VERSION_MASK
* To be consistent with other SoC's, introduced VI6_IP_VERSION_SOC_G2L
for RZ/G2L SoC's.
v3->v4:
* Added Rb tag from Geert
* Add switch() for LIF0 buffer attribute handling for RZ/G2L and V3M
v2->v3:
* Fixed version comparison in vsp1_lookup()
v1->v2:
* 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:
* Used data pointer containing info structure to retrieve version information
