Two variables named master_int and sleepseq_val, were just
declared without initialization. Pointers to these variables
were passed to mfd read function. After that these variables
were used for some of the logical operations.

Though logically there is nothing wrong, compiler is complaining
that the variables may be used uninitialized.

Hence fixing these warning messages by initializing them.

With this patch children no longer need IRQ resources as it's easier
for them to use regmap_get_virq. So we can remove the resources

Before the AB8500 had its own IRQ domain, the IRQ handler would take
the fired local IRQ (hwirq) and add it to the irq_base to convert it
to an IRQ number which Linux would understand (virq). However, the
IRQ base is not always used anymore since we can make use of Linear
domains. It's better to use the AB8500 hwirq -> virq mapping helper
function to convert them instead. That's what we do here.
