Having to call qe_ic_init() from platform-specific code makes it awkward to allow building the QE drivers for ARM. It's also a needless duplication of code, and slightly error-prone: Instead of the caller needing to know the details of whether the QUICC Engine High and QUICC Engine Low are actually the same interrupt (see e.g. the machine_is() in mpc85xx_mds_qeic_init), just let the init function choose the appropriate handlers after it has parsed the DT and figured it out. If the two interrupts are distinct, use separate handlers, otherwise use the handler which first checks the CHIVEC register (for the high priority interrupts), then the CIVEC. All existing callers pass 0 for flags, so continue to do that from the new single caller. Later cleanups will remove that argument from qe_ic_init and simplify the body, as well as make qe_ic_init into a proper init function for an IRQCHIP_DECLARE, eliminating the need to manually look up the fsl,qe-ic node.
