arm-common: Reorder gicv2_cpu_init
This pulls CPU ID validation and gicv2_target_cpu_map setup to the
beginning of gicv2_cpu_init so that we can fail early if needed, before
any changes to the hardware configuration are made. This will also help
when introducing SDEI-based management interrupts.

arm-common: Add SDEI-based management event injection support
This is the first building block for switching to management interrupts
using the Software Delegated Exception Interface (SDEI) which will allow
to pass the GICC to the guest.
In this step, the feature flag is introduced - but not yet set -, and
arch_send_event is augmented with sending the event via
SDEI_EVENT_SIGNAL, software event 0.

arm-common: Pass through GIC CPU interface in SDEI mode
When SDEI is used for management interrupts, we can give the gicc

initializations and to map the physical gicc-v2 into the cell or to not
enable ICH_HCR_EN in case of gic-v3. Furthermore, injected interrupts
now have to be sent as physical SGI to the target, rather than being
queued for the virtual interface.

arm64: Add SDEI-based management interrupt handling
This brings the arm64-specific bits to handle management interrupts sent
via SDEI.
The pattern for processing them is derived from NMI-based injection on
x86: The SDEI event can come asynchronously at any time while in EL2,
EL1 or EL0. To avoid having to synchronize with running EL2, translate
it into a trap that is triggered on EL1/0 reentry. We use an invalid
VTCR_EL2 value for this and set the per-cpu sdei_event flag. When EL2
finds this flag set on handling the trap, it kicks off SGI_EVENT
handling and restores VTCR_EL2.

arm-common: Handle SDEI case in PSCI CPU_SUSPEND
When suspending the CPU while interrupts are passed through, we cannot
simply call wfi as EL2 is not receiving interrupts as wakeup events -
the CPU would starve.
Factor out arm_cpu_passthru_suspend to handle this case by enabling IMO
and FMO before calling wfi. That ensures that EL2 will resume, and as
interrupts are off in that mode, the events will simply be carried to
EL1 when clearing IMO/FMO before returning.
For ARM, arm_cpu_passthru_suspend remains empty as there is no SDEI.

Check UART UCR1_UARTEN bit before writing data
There is frequent start/shutdown operation in kernel reboot process.
And at the end of kernel reboot, kernel will switch to use console
output,saying imx_console_write on i.MX8MM.
imx_console_write will save/restore uart configuration.
However before imx_console_write the UCR1_UARTEN already set to 0.
when restore, it is also 0. Then when we runs into jailhouse
disable, jailhouse write to uart will trigger hardware exceptions.
So let's add a check.
However to hypervisor itself, there is still risk that
kernel disable uart, whenh jailhouse is going to write
data registers even with this patch applied.
There is no good way to avoid such contention,
the best way to avoid such issue is that
use a different uart from Linux or remove
`.type = JAILHOUSE_CON_TYPE_IMX,` from configs/arm64/imx8mm.c.
Remove `.type = JAILHOUSE_CON_TYPE_IMX,` means
jailhouse hypervisor will not output to uart, but you still
could see jailhouse log by `cat /dev/jailhouse`

core: avoid overflow in paging_destroy
It is possible for the ending address in paging_destroy to overflow to
exactly 0. For example, in a build with 32-bit addresses, a request to
unmap 512MB at 0xe0000000 will result in an overflow (0xe0000000 +
0x20000000 = 0x100000000 which exceeds 32 bits).
This overflow can be avoided by comparing the last address in the
region to be unmapped rather than the first address to not be
unmapped.
