Add support for PMIC5 Gen2 ADC_TM, used on PMIC7 chips. It is a
close counterpart of PMIC7 ADC and has the same functionality as
PMIC5 ADC_TM, for threshold monitoring and interrupt generation.
It is present on PMK8350 alone, like PMIC7 ADC and can be used
to monitor up to 8 ADC channels, from any of the PMIC7 PMICs
having ADC on a target, through PBS(Programmable Boot Sequence).

platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static
allocation of IRQ resources in DT core code, this causes an issue
when using hierarchical interrupt domains using "interrupts" property
in the node as this bypasses the hierarchical setup and messes up the
irq chaining.

In preparation for removal of static setup of IRQ resource from DT core
code use platform_get_irq_optional().

With the new OS handshake introduced by commit: "c7ff2976 ("thermal:
int340x: Update OS policy capability handshake")", the "enabled" thermal
zone mode doesn't work in the same way as previously.

The "enabled" mode fails with -EINVAL when the new handshake is used.

To address this issue, when the new OS UUID mask is set:

 - When the mode is "enabled", return 0 as the firmware already has the
   latest policy mask.

 - When the mode is "disabled", update the firmware with the UUID mask
   of zero.

This way, the firmware can take over the thermal control.

Also reset the OS UUID mask, which allows user space to update with new
set of policies.

Interrupt handler bad_flp_intr() may cause a UAF on the recently freed
request just to increment the error count.  There's no point keeping
that one in the request anyway, and since the interrupt handler uses a
static pointer to the error which cannot be kept in sync with the
pending request, better make it use a static error counter that's reset
for each new request.  This reset now happens when entering
redo_fd_request() for a new request via set_next_request().

One initial concern about a single error counter was that errors on one
floppy drive could be reported on another one, but this problem is not
real given that the driver uses a single drive at a time, as that
PC-compatible controllers also have this limitation by using shared
signals.  As such the error count is always for the "current" drive.
