based Rhine architecture.

Implement TX enqueue logic for WCN6450. There are no host facing
UMAC HW blocks in WCN6450. Driver enqueues all TX packets to
copy engine (CE) over the copy engine channel that is mapped to
HTT_DATA2_MSG_SVC service.
Changes are specific to WCN6450 and hence implement the logic
in the arch specific code.

WCN6450 is a chip based on Rhine architecture. Unlike LI/BE targets,
chipsets based on Rhine (RH) do not have host facing UMAC HW blocks.
Their corresponding SRNG interfaces are also removed. The functionality
of these UMAC HW blocks is replaced with a software implementation in
the firmware. Communication between the driver and firmware will happen
over copy engine (CE).
Although there are no host facing UMAC HW blocks, the CE hardware used
in WCN6450 expects the host driver to use the TX descriptor (HW) format
of LI targets during TX packet enqueue. Therefore it is required to
create a new pool of TX descriptors (HW) pool for WCN6450 that is used
during TX.
The logic to create/free/init/deinit these descriptors is specific
to WCN6450/Rhine, therefore it is implemented in architecture specific
Rhine code.
Introduce new APIs in struct dp_arch_ops {} to allocate and free
arch specific TX descriptors. These ops will be no-op for LI/BE
architectures.
Also for Rhine targets, allocate/free other TX descriptors like TX EXT &
TSO descriptors as part of the arch APIs.

RHINE is soft UMAC based architecture which is not having
REO block, all the REO functionality will be implemented
in F.W and host level. Host will get the RX packets in
CE-RX rings in HTT format, to reap RX packets new HTT
messages will be extracted and parsed.
So implement RX handling based on new softumac architecture for RHINE.

This change introduces new RHINE architecture specific DP files.
RHINE is new SOFTUMAC based architecture, unlike LI/BE targets
all the HW UMAC functionality will be replaced with software base
UMAC functionality. So current RHINE arch specific implementation
is aligned to softumac based implementation.
