Current implementation of __vmread() returns the result via pointer argument
which leads to having excess code in some places.
Update the signature of __vmread() to return `unsigned long` and drop the
pointer argument as per suggestion in [1].
Rename __vmread() to vmread() as

Currently, hypervisor code has two different non-system domain ID allocation
algorithms:
(a) Arm port allocates IDs sequentially based on max_init_domid;
(b) x86 has another algorithm implementation embedded into
XEN_DOMCTL_createdomain; does not use max_init_domid,

Convert the DR7 type to `unsigned int` and fix the accesses where necessary.

The patch series reworks __vmread() by introducing a new cleaner API.
Patch 1 introduces a new vmread() call which will be a replacement for
__vmcall().
Patch 2 updates the type of arch_vcpu->dr7 field.
Patch 3 replaces __vmread() with vmread().

From: Denis Mukhin
Use vmread() instead of __vmread() as per suggestion in [1] everywhere in the
VT-x code.
Remove __vmread() and update ECLAIR configuration.

guest_console_write() duplicates the code from __putstr(), eliminate code
duplication.
Introduce console_puts() for writing a buffer to console devices.
Also, introduce internal console flags to control which console devices
should be used.

The patch series introduces a few cleanups aimed at reducing code duplication
in the console driver.
Originally, patches 2 and 3 were part of NS16550 emulator v3 series [1].
Patch 1 removes some code duplication for logging via conring facility.
Patch 2 (see [2]) removes code duplication between
