karo: tx48: remove the 'interrupts' property from LTC3589 node for AM335x silicon...

This silicon rev. has the polarity of the EXTINTn pin inverted
wrt. the spec. with no useable workaround. Remove the 'interrupts'
property from the ltc3589 DT node, so that the LTC driver will operate
in polling mode.
