irqchip/irq-mvebu-icu: Fix access to msi_data from irq_domain::host_data

commit 987f379b54091cc1b1db986bde71cee1081350b3 upstream.

mvebu_icu_translate() incorrectly casts irq_domain::host_data directly to
mvebu_icu_msi_data. However, host_data actually points to a structure of
type msi_domain_info.

This incorrect cast causes issues such as the thermal sensors of the
CP110 platform malfunctioning. Specifically, the translation of the SEI
interrupt to IRQ_TYPE_EDGE_RISING fails, preventing proper interrupt
handling. The following error was observed:

  genirq: Setting trigger mode 4 for irq 85 failed (irq_chip_set_type_parent+0x0/0x34)
  armada_thermal f2400000.system-controller:thermal-sensor@70: Cannot request threaded IRQ 85

Resolve the issue by first casting host_data to msi_domain_info and then
accessing mvebu_icu_msi_data through msi_domain_info::chip_data.
