HV: move dmar info definition to board.c

Browse Source 
The DMAR info is board specific so move the structure definition to board.c.
As a configruation file, the whole board.c could be generated by acrn-config
tool for each board.

Please note we only provide DMAR info MACROs for nuc7i7dnb board. For other
boards, ACPI_PARSE_ENABLED must be set to y in Kconfig to let hypervisor parse
DMAR info, or use acrn-config tool to generate DMAR info MACROs if user won't
enable ACPI parse code for FuSa consideration.

The patch also moves the function of get_dmar_info() to vtd.c, so dmar_info.c
could be removed.

Tracked-On: #3977
