PCI: aardvark: Fix setting MSI address
MSI address for receiving MSI interrupts needs to be correctly set before
enabling processing of MSI interrupts.
Move code for setting PCIE_MSI_ADDR_LOW_REG and PCIE_MSI_ADDR_HIGH_REG
from advk_pcie_init_msi_irq_domain() to advk_pcie_setup_hw(), before
enabling PCIE_CORE_CTRL2_MSI_ENABLE.
After this we can remove the now unused member msi_msg, which was used
only for MSI doorbell address. MSI address can be any address which cannot
be used to DMA to. So change it to the address of the main struct advk_pcie.
