pinctrl: equilibrium: fix warning trace on load

The callback functions 'eqbr_irq_mask()' and 'eqbr_irq_ack()' are also
called in the callback function 'eqbr_irq_mask_ack()'. This is done to
avoid source code duplication. The problem, is that in the function
'eqbr_irq_mask()' also calles the gpiolib function 'gpiochip_disable_irq()'

This generates the following warning trace in the log for every gpio on
load.

In an other driver (drivers/pinctrl/starfive/pinctrl-starfive-jh7100.c) the
interrupt is not disabled here.

To fix this, do not call the 'eqbr_irq_mask()' and 'eqbr_irq_ack()'
function. Implement instead this directly without disabling the interrupts.
