The bcm2835-unicam driver calls the clk_set_min_rate() function, which
is declared but not implemented on platforms that don't provide
COMMON_CLK. This causes linkage failures with some configurations.
Fix it by depending on COMMON_CLK. This only slightly restricts
compilation testing, but not usage of the driver as all platforms on
which the hardware can be found provide COMMON_CLK.

Before this commit on probe() the driver would do:
reset=1 // from probe() calling gpiod_get(GPIOD_OUT_HIGH)
reset=0 // from resume()
msleep(20) // from resume()
So if reset was 0 before getting the GPIO the reset line would only be
driven high for a very short time and sometimes there would be errors
reading the id register afterwards.
Add a msleep(20) after getting the reset line to ensure the sensor is
properly reset:
reset=1 // from probe() calling gpiod_get(GPIOD_OUT_HIGH)
msleep(20) // from probe()
reset=0 // from resume()
msleep(20) // from resume()

platform_get_irq() cannot return the value 0. It will either return a non-zero
irq or a errcode.
If a errcode is returned, we need to populate the error code upwards. It will
give a more accurate reason of why it failed to the caller, who might decide
to retry later.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

The ipu6 driver allocated vmalloc memory for the firmware if
request_firmware() somehow managed not to use vmalloc to allocate it.
Still how the memory is allocated by request_firmware() is not specified
in its API, so be prepared for kmalloc-allocated firmware, too. Instead of
allocating new vmalloc-backed buffer for the firmware, obtain the pages
from virtual addresses instead.

When building for LoongArch with clang 18.0.0, the stack usage of
probe() is larger than the allowed 2048 bytes:
drivers/media/dvb-frontends/mxl5xx.c:1698:12: warning: stack frame size (2368) exceeds limit (2048) in 'probe' [-Wframe-larger-than]
1698 | static int probe(struct mxl *state, struct mxl5xx_cfg *cfg)
| ^
1 warning generated.
This is the result of the linked LLVM commit, which changes how the
arrays of structures in config_ts() get handled with
CONFIG_INIT_STACK_ZERO and CONFIG_INIT_STACK_PATTERN, which causes the
above warning in combination with inlining, as config_ts() gets inlined
into probe().
This warning can be easily fixed by moving the array of structures off
of the stackvia 'static const', which is a better location for these
variables anyways because they are static data that is only ever read
from, never modified, so allocating the stack space is wasteful.
This drops the stack usage from 2368 bytes to 256 bytes with the same
compiler and configuration.

Keep track if cec_claim_log_addrs() is running, and return -EBUSY
if it is when calling CEC_ADAP_S_LOG_ADDRS.
This prevents a case where cec_claim_log_addrs() could be called
while it was still in progress.
