Multiple files in this driver fail to build because of missing
header inclusions:
drivers/media/platform/qcom/camss/camss-csiphy-2ph-1-0.c: In function 'csiphy_hw_version_read':
drivers/media/platform/qcom/camss/camss-csiphy-2ph-1-0.c:31:18: error: implicit declaration of function 'readl_relaxed'; did you mean 'xchg_relaxed'? [-Werror=implicit-function-declaration]
drivers/media/platform/qcom/camss/camss-csiphy-3ph-1-0.c: In function 'csiphy_hw_version_read':
drivers/media/platform/qcom/camss/camss-csiphy-3ph-1-0.c:52:2: error: implicit declaration of function 'writel' [-Werror=implicit-function-declaration]
Add linux/io.h there and in all other files that call
readl/writel and related interfaces.

Add support for 10-bit packed V4L2_PIX_FMT_Y10P (on 8x16 and 8x96)
and unpacked V4L2_PIX_FMT_Y10 (on 8x96 only) pixel formats.

As the 8x16 and 8x96 support different formats, separate the
arrays which contain the supported formats. For the VFE also
add separate arrays for RDI and PIX subdevices.

ISPIF hardware modules on 8x16 and 8x96 are similar. However on
8x96 the ISPIF routes data to two VFE hardware modules. Add
separate interrupt handler for 8x96 to handle the additional
interrupts.

There is a PM domain for each of the VFE hardware modules. Add
support for basic runtime PM support to be able to control the
PM domains. When a PM domain needs to be powered on - a device
link is created. When a PM domain needs to be powered off -
its device link is removed. This allows separate and
independent control of the PM domains.
Suspend/Resume is still not supported.

Add structs with 8x96 resources. As the number of CSIPHY, CSID
and VFE hardware modules is different on 8x16 and 8x96 select
the number at runtime and allocate needed structures
dynamically.
