power: supply: axp288_charger: Fix unchecked return value
commit c3422ad5f84a66739ec6a37251ca27638c85b6be upstream.
Currently there is no check on platform_get_irq() return value
in case it fails, hence never actually reporting any errors and
causing unexpected behavior when using such value as argument
for function regmap_irq_get_virq().
Fix this by adding a proper check, a message reporting any errors
and returning *pirq*
Addresses-Coverity-ID: 1443940 ("Improper use of negative value")
Fixes: 843735b788a4 ("power: axp288_charger: axp288 charger driver")
