The code obtaining the ADC channels is outdated: it is
trying to work around the IIO subsystem not returning
the right -EPROBE_DEFER error code. Fix this up
by using the dev_err_probe() helper so we defer silently
where appropriate and not bail out if the IIO core
returns -EPROBE_DEFER as happens now.

Since these IRQs are cascaded from a nested IRQ, the
generic IRQ system detects this and refuse to deliver
a fastpath IRQ in response to request_irq():

  nested = irq_settings_is_nested_thread(desc);
  if (nested) {
          if (!new->thread_fn) {
                  ret = -EINVAL;
                  goto out_mput;
          }
   (...)

Threaded IRQs work just as well so let's just request
threaded IRQs. One of the IRQs are alread requested
as threaded anyways.

Make sure the threaded IRQs requested by the charger are
flagged as "oneshot". Usually this is what you want, and
since the interrupts are shared with the USB phy on the
AB8500 we will get a conflict like this if we don't,
since the phy request them threaded oneshot:

genirq: Flags mismatch irq 83. 00004084 (USB_LINK_STATUS
  vs. 00006084 (usb-link-status)

Commit 9c80662a ("power: supply: axp288_charger: Add special handling
for HP Pavilion x2 10") added special handling for HP Pavilion x2 10
models which use the weird combination of a Type-C connector and the
non Type-C aware AXP288 PMIC.

This special handling was activated by a DMI match a the product-name
of "HP Pavilion x2 Detachable". Recently I've learned that there are
also older "HP Pavilion x2 Detachable" models with an AXP288 PMIC +
a micro-usb connector where we should not activate the special handling
for the Type-C connectors.

Extend the matching to also match on the DMI board-name and match on the
2 boards (one Bay Trail based one Cherry Trail based) of which we are
certain that they use the AXP288 + Type-C connector combination.

Note the DSDT code from these older (AXP288 + micro-USB) models contains
some AML code (which never runs under Linux) which reads the micro-USB
connector id-pin and if it is pulled to ground, which would normally mean
the port is in host mode!, then it sets the input-current-limit to 3A,
it seems HP is using the micro-USB port as a charging only connector
and identifies their own 3A capable charger though this hack which is a
major violation of the USB specs. Note HP also hardcodes a 2A limit
when the id-pin is not pulled to ground, which is also in violation
of the specs.

I've no intention to add support for HP's hack to support 3A charging
on these older models. By making the DMI matches for the Type-C equipped
models workaround more tighter, these older models will be treated just
like any other AXP288 + micro-USB equipped device and the input-current
limit will follow the BC 1.2 spec (using the defacto standard values
there where the BC 1.2 spec defines a range).
