The carved out or allocated memory may not be configured to be
accessible by both the owner and consumer vms. Add support to share
memory through hyp_assign_phy() and assign a label to the resultant
memparcel through hh_rm_mem_qcom_lookup_sgl().
This sharing sequence should only be done by the owner of the reserved
memory region. Currently we indicate this with the qcom,primary tag in
device tree.

Store the haven label so it can be used for other haven resources such
as attaching it to memparcels that are shared.

Add support for the primary vm to read the vm peer name from device
tree. This information is needed to share memory to the peer vm.

The ready state gives clients in the primary vm a chance to share
resources before the vm is started and set to running state. This
window is currently missing because guestvm_loader starts the vm
directly after subsystem_get().
Make the guestvm boot code wait for the HH_RM_VM_STATUS_READY callback
before starting the vm. This allows drivers that need to share
resources a chance to do so instead of racing with guestvm_loader.
Drivers can register with the rm notifier chain at a higher priority
than 0 to be called first.
This change can eventually be replaced by a separate driver or notifier
chain managed by guestvm_loader to provide better synchronization
methods compared to notifier chain priority.

For voice usecases, while opening the slimbus
slave ports, currently data format LPCM(1) is used.
SB master uses data format as unspecified(0). SB master's
data format overwrites the slave side configuration.
In the rare cases, this mismatch may lead to pop sound
in SCO Tx(BT FW->LPASS) at the very beginning when
voice is switched from speaker/handset to BT from call UI.
To fix this, use the data format as unspecified during
opening of the slimbus slave ports for voice cases.

AB voting is done in multiples of BW_STEP. Using a big
BW_STEP can result in AB overvoting because of roundup.
Use BW_STEP as 50 instead of 160. This will reduce AB
overvoting and will improve power.
