VIRT_IOAPIC_REG_BASE and VIRT_MISC_REG_BASE.

Now VIRT_GED_CPUHP_ADDR is not aligned to 4 bytes, but if Linux kernel
is built with ACPI_MISALIGNMENT_NOT_SUPPORTED, it assumes the alignment,
otherwise we get ACPI errors at boot phase:
ACPI Error: AE_AML_ALIGNMENT, Returned by Handler for [SystemMemory] (20250404/evregion-301)
ACPI Error: Aborting method \_SB.CPUS.CSTA due to previous error (AE_AML_ALIGNMENT) (20250404/psparse-529)
ACPI Error: Aborting method \_SB.CPUS.C000._STA due to previous error (AE_AML_ALIGNMENT) (20250404/psparse-529)
ACPI Error: Method execution failed \_SB.CPUS.C000._STA due to previous error (AE_AML_ALIGNMENT) (20250404/uteval-68)
VIRT_GED_MEM_ADDR and VIRT_GED_REG_ADDR are already aligned now, but use
QEMU_ALIGN_UP() to explicitly align them can make code more robust.

dmsi feature is added in LoongArchVirtMachinState, and it is used
to check whether virt machine supports the directy Message-Interrupts.
and by default set dmsi with ON_OFF_AUTO_AUTO.
LoongArchVirtMachineState adds misc_feature and misc_status for misc
features and status. and set the default dintc feature bit.

And move functions relative with fdt table building to the file.
It is only code movement and there is no function change.

Rename LoongArchMachineState with LoongArchVirtMachineState, and change
variable name LoongArchMachineState *lams with LoongArchVirtMachineState
*lvms.
Rename function specific for virtmachine loongarch_xxx()
with virt_xxx(). However some common functions keep unchanged such as
loongarch_acpi_setup()/loongarch_load_kernel(), since there functions
can be used for real hw boards.
