power: bcl_peripheral: Move BCL interrupts to level based



BCL driver was using edge triggered interrupt, which allows
the Linux interrupt framework to flag pending interrupts
after BCL interrupts are disabled. This pending interrupt
will trigger a false trip as soon as the interrupt is enabled.
To fix this, move BCL Ibat and Vbat interrupts from edge
triggered to level triggered. This will eliminate any pending
interrupts that will cause unexpected behavior in BCL
driver.
