Currently, the clients of the hh_msgq driver would allocate buffers,
fill with data and call hh_msgq_send(). Upon success, hh_msgq_send()
would be freeing the buffer, while in the case of failure, the clients
are responsible for it. However, this approach of buffer management is
not symmetric and could be confusing for the clients. Hence, let the
clients take full ownership of the buffers- allocating and freeing.
Also make changes to the affected client drivers.

It's a highly likely situation that the clients call hh_msgq_recv()
from a thread in a polling fashion, and these threads are spawned
during client driver's initialization. Hence, it's possible that
the cap-ids for the message queues will not be ready so early and
the clients would end up continuously spinning on hh_msgq_recv(),
receiving the error -EAGAIN. To avoid this situation, put the
client process onto a wait-queue until the cap-ids are ready.
Although a little unlikely, to satisfy the symmetry, add the same
provision for the callers of hh_msgq_send() as well.

There's a potential chance that the clients can request to
send or receive the data from an interrupt context. Hence,
convert the cap_entry_lock from mutex to a spinlock.

Currently, the cap-id for Tx and Rx of the message-queue are
initialized with 0. However, 0 is a valid value for cap-id.
A better value to initialize the cap-id is with U64_MAX. Hence,
make corrections to use U64_MAX, defined as HH_CAPID_INVAL, in
the message-queue driver.

Current driver will check PCIe link status by reading PCIe config space
before updating time sync registers. However, there is a drawback to use
PCIe API pci_read_config_word() to access config space since it will
disable interrupt and then perform read. If PCIe link is in L1 or L1ss
state, there may be more than 4ms needed to change the link state to L0
in order to access so it will cause jank for other time critical tasks.
Hence make sure PCIe link is in L0 state before updating time sync
registers instead of checking config space.
