1. In lowmem profiles the number of tx_desc in 4th pool is reduced to
quarter for memory optimizations.
Added new API dp_get_updated_tx_desc which will return the desc value
from INI based on the flag DP_TX_DESC_POOL_OPTIMIZE.
2. Changes to introduce new INI to get reduced desc value for 4th tx
desc pool.
This helps optimize 0.75M per SOC in lowmem profiles.

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.

Currently, memory for all kinds of TX descriptors (TX EXT,
TSO etc) are allocated/initialised at once during the driver
init and freed/deinitialised during the driver deinit.
This logic is not suitable for WCN6450.
In the case of WCN6450, the size of the TX descriptor pool is
not known to the driver during load time; Firmware provides
the size of the descriptor pool via HTT_T2H_MSG_TYPE_FLOW_POOL_MAP
message post VDEV creation.
In order to add the support of WCN6450, it is required to
refactor the TX descriptor alloc/free/init/deinit logic.
Changes will not have any impact on the other supported hardware.

The kernel-doc script identified a large number of documentation
issues in dp/wifi3.0/dp_tx_desc.[ch], so fix those issues. In
addition, there are a number of instances where public functions have
their implementation documented instead of having their interface
documented, so move that documentation.

Cleanup the tx desc clean up logic used in

The excess code being removed tries to
get the next descriptor address in boundary
conditions is not useful, as the descriptor
extracted this way will be overwritten
immediately in the beginning of next iteration
of the loop.

DP uses multi page allocation for tx/rx descriptor.
ID and offset mask of decriptor is based on 4096 which
couples with Kernel's MMU PAGE_SIZE. This cause trouble
when deploy driver on none-4K page size kernel.
Set qdf_dp_blockmem_size to 4096 so that DP won't
depend on kernel page size.

- Add cdp soc init/deinit and cdp pdev init/deinit that
