ARM: ux500: Fix PMU IRQ regression
Commit 2b05f6ae1ee5 ("ARM: ux500: remove PMU IRQ bouncer") deleted some code to bounce and work around the weird PMU IRQs in the DB8500 ASIC, but did a semantic mistake: since the auxdata was now unused, the call to of_platform_populate() was removed, but this does not work: the default platform population will only kick in if .init_machine() is assigned NULL, and since the U8540 was still using the callback that was not the case. Fix this by reinstating the call to of_platform_populate(), but pass NULL as auxdata.
