Viktor Sjölind 5f51e4a762 pci.c: assert MSIX table count <= config max
Assert that PCI devices discovered while booting the hypervisor do not
have more table entries than allowed by the compile-time configuration
(CONFIG_MAX_MSIX_TABLE_NUM).

The case were `msix.table_count` > `CONFIG_MAX_MSIX_TABLE_NUM` is fatal
since the init function in the handler for MSI-X (vmsix_init) only looks
at `table_count` when populating the table. Since
`CONFIG_MAX_MSIX_TABLE_NUM` is the max size of the table array entry in
the pci_msix struct. This will cause the msix handler to write outside of
the table array.

Mingqiang Chi 511d4c158b hv:cleanup console.h
--move several uart API declarations from console.h to uart16550.h
 --move several shell API declarations from console.h to shell.h
 --add dbg_cmd.h, move 'handle_dbg_cmd' declaration from console.h
   to dbg_cmd.h
 --move debug/uart16550.h to include/debug/uart16550.h since some
   uart APIs will be called by external files

dongshen 1454dd371d HV: this patch fixes bar address non-zero checking for 64-bit bars
For 64-bit bars, previously the code will do bar size calculation only if the
lower 32-bit bar address is nonzero, changed to do bar size calculation when the whole
64-bit bar address is nonzero.

Victor Sun f082176df0 HV: init ptdev bar during runtime for partition mode
Current pt devices bar info for partion mode is hardcoded in
vm_description.c, now we remove the hardcoded info and parse the bar
info during pt devices init.
