When registering a power-supply device, either a of_node or the more
recent fwnode can be supplied. Since fwnode can also contain an of_node,
let's try to get rid of it.

The check for whether a charger supports the requested
battery voltage was incorrectly added to the
`ip5xxx_battery_get_voltage_max()` function, instead of
`set_voltage_max()`. This commit fixes it.

On parts where there is no status register, check the Charge End
bit to set charging/not charging status. Fullness, trickle charge
status, discharging etc. cannot be determined from just this bit.

Some parts may not have certain control bits. These bits
however may be non-essential to the system's operation,
as the default behaviour is the one we would set anyways,
or the bits are not applicable for said part (e. g. enabling
NTC on a part without an NTC pin, or one where it cannot
be disabled via registers anyways).

The IP53xx series [1] has a much different register
layout than the 51xx/52xx [2] currently supported
by this driver. To accommodate supporting the former,
refactor the code to use the flexible regmap_field API.

If ADC read returns an error, the return value was silently ignored,
execution continued and an uninitialized value and a return code of 0
was passed back to userspace. The only exception was
POWER_SUPPLY_PROP_CONSTANT_CHARGE_CURRENT, which bailed out correctly.
Fix returns for the other cases as well.

When current is larger than ~2A, the multiplication in current_now
property overflows and the kernel reports invalid negative current
value. Change the numerator and denominator while preserving their
ratio to allow up to +-6A before the overflow.

This driver supports several chip variants which all share the same I2C
register interface. Since the chip will turn off and become inaccessible
under conditions outside of software control (e.g. upon button press or
input voltage removal), some special handling is needed to delay the
initialization of the IC until it is accessible.
