cd42f8023f media: rockchip: rkisp1: add support for v12 isp variants
The rkisp1 evolved over soc generations and the rk3326/px30 introduced
the so called v12 - probably meaning v1.2.

Add the new register definitions.

dce8ccb232 media: rockchip: rkisp1: add prefixes for v10 specific parts
The rkisp1 evolved over soc generations and the rk3326/px30 introduced
the so called v12 - probably meaning v1.2.

In a first step adapt the affected v10 parts to give them a
matching suffix to enable us to add v12 variants later on.

962fb14068 media: rockchip: rkisp1: make some isp-stats functions variable
The isp block evolved in subsequent socs, so some functions
will behave differently on newer variants.

Therefore make it possible to override the needed stats functions.

07e59d91e7 media: rkisp1: remove field 'vaddr' from 'rkisp1_buffer'
The virtual address can be accessed using vb2_plane_vaddr
therefore there is no need to save it in an extra field in
'rkisp1_buffer'. Remove it.

ef357e02b6 media: rockchip: rkisp1: extend uapi array sizes
Later variants of the rkisp1 block use more entries in some arrays:

RKISP1_CIF_ISP_AE_MEAN_MAX                 25 -> 81
RKISP1_CIF_ISP_HIST_BIN_N_MAX              16 -> 32
RKISP1_CIF_ISP_GAMMA_OUT_MAX_SAMPLES       17 -> 34
RKISP1_CIF_ISP_HISTOGRAM_WEIGHT_GRIDS_SIZE 25 -> 81

and we can still extend the uapi during the 5.11-rc cycle, so do that
now to be on the safe side.

V10 and V11 only need the smaller sizes, while V12 and V13 needed
the larger sizes.

When adding the bigger sizes make sure, values filled from hardware
values and transmitted to userspace don't leak kernel data by zeroing
them beforehand.

hist_bins is an array of type __u32. Each entry represent
a 20 bit fixed point value as documented inline.
The cast to u8 when setting the values is wrong. Remove it.

All the items in the TODO list were addressed, uapi was reviewed,
documentation written, checkpatch errors fixed, several bugs fixed.

There is no big reason to keep this driver in staging, so move it out.
