[media] m5mols: Don't ignore v4l2_ctrl_handler_setup() return value
v4l2_ctrl_handler_setup() may fail so check its return value when
restoring controls after device is powered on. While at it simplify
the m5mols_restore_function() a bit.

[media] m5mols: Add support for the system initialization interrupt
The M-5MOLS internal controller's initialization time depends on the
hardware and firmware revision. Currently the driver just waits for
worst case time period, after applying the voltage supplies, for
the device to be ready. The M-5MOLS supports "System initialization"
interrupt which is triggered after the controller finished booting.
So use this interrupt to optimize the initialization sequence.
After the voltage supplies are applied the I2C communication will
fail, until the internal controller initializes to Flash Writer
state. For the period when the I2C is not accessible use the
isp_ready flag to suppress the error logs.

[media] m5mols: Remove mode_save field from struct m5mols_info
There is no need to keep this in the drivers' private data structure,
an on the stack variable is enough. Also simplify a bit the ISP state
switching function.

[media] m5mols: Improve the interrupt handling routines
The work struct based interrupt handling is not flexible enough
as the M-5MOLS control sequence involves I2C access sequences
before and after an interrupt is generated. A single waitqueue is
enough for the job so remove the work struct based code.

[media] m5mols: Extend the busy wait helper
Make m5mols_busy_wait function jiffies based rather than relying
on some fixed number of I2C read iterations while busy waiting
for the device to execute a request. With fixed number of iterations
we may be getting different wait times, depending on the I2C speed.
In some conditions we have to wait even if the I2C communications
fails, in those cases M5MOLS_I2C_RDY_WAIT_MASK should be passed
as the mask argument to m5mols_busy_wait().

[media] m5mols: Simplify the I2C registers definition
The redundant definitions of the m5mols I2C register addresses within
the pages (categories) are removed. In place of symbolic definitions
plain numbers are used which simplifies the code and eases identifying
the registers in the documentation.
Also make the m5mols_busy() function accept I2C_REG() value as a register
address, like all other functions, rather than using the category and
command values.

[media] m5mols: Fix set_fmt to return proper pixel format code
In case pixel format is modified in set_fmt by the driver,
the changes are not propagated back to the caller. Fix this
by adjusting passed data for TRY and ACTIVE format.
Also remove redundant pixel format code information from
struct m5mols_info, it's already available in 'ffmt' array.
Remove pad number validation in set/get_fmt, this is already
done in the core.

[media] m5mols: add m5mols_read_u8/u16/u32() according to I2C byte width
For now, the m5mols_read() share in case of I2C packet 1, 2, 4 byte(s) width.
So, this commit adds 3 functions - m5mols_read_u8/u16/u32() according to byte
width of I2C packet. And, the u32 variables in spite of u8 or u16 for fitting
to m5mols_read() having no choice, is replaced to have original byte width
like u8, u16, u32 as same reason.
