spi: bcm-qspi: clear MSPI spifie interrupt during probe
Intermittent Kernel crash has been observed on probe in bcm_qspi_mspi_l2_isr() handler when the MSPI spifie interrupt bit has not been cleared before registering for interrupts. Fix the driver to move SoC specific custom interrupt handling code before we register IRQ in probe. Also clear MSPI interrupt status resgiter prior to registering IRQ handlers.
