Since a few called V4L2 functions operate with fwnode arguments the change

The camss_parse_endpoint_node() function is called once by camss_probe(),

remote devices, so it makes sense to remove the related computation from
the function.

vfe_isr() iterates using MSM_VFE_IMAGE_MASTERS_NUM(7) as the loop
bound and passes the index to vfe_isr_reg_update(). However,
vfe->line[] array is defined with VFE_LINE_NUM_MAX(4):
struct vfe_line line[VFE_LINE_NUM_MAX];
When index is 4, 5, 6, the access to vfe->line[line_id] exceeds
the array bounds and resulting in out-of-bounds memory access.
Fix this by using separate loops for output lines and write masters.

Some Qualcomm regulators are configured with initial mode as
HPM (High Power Mode), which may lead to higher power consumption.
To reduce power usage, it's preferable to set the initial mode
to LPM (Low Power Mode).
To ensure the regulator can switch from LPM to HPM when needed,
this patch adds current load configuration for CAMSS CSIPHY.
This allows the regulator framework to scale the mode dynamically
based on the load requirement.
The current default value for current is uninitialized or random.
To address this, initial current values are added for the
following platforms:
MSM8916, MSM8939, MSM8953, MSM8996, QCM2290, SDM670, SM8250, SC7280,
SM8550, SM8650, QCS8300, SA8775P and X1E80100.
For SDM660, SDM845, SC8280XP the value is set to 0,
indicating that no default current value is configured,
the other values are derived from the power grid.

This has been done in the driver .remove() right from the beginning, but
error paths on .probe() shall also be fixed.

The moving of init sequence hook from gen2() to subdev_init() doesn't
account for gen1 devices such as SDM660 and SDM670. The switch should find
the right offset for gen2 PHYs only, not reject gen1. Remove the default
error case to restore gen1 CSIPHY support.

The libcamera plugin for Pipewire may keep an open file descriptor to
the video device, even while streaming. This simplifies its operation,
as it only needs to keep track of a number instead of a file path. When
the video device is open but not streaming, the pipeline can be powered
off. Move the pipeline power management to the prepare_streaming and
unprepare_streaming functions.
