Improper/incomplete DMA by the target affects the functionality of modules
that are using DBR framework. Add debug infrastructure to poison DBR
buffers with a given poison value before handing buffers over to
the target. Buffer owner modules can explicitly check for the poison
value in order to detect the improper DMA.
All modules that use DBR framework can use this debug infrastructure.

Add debug infrastructure to track the movement of head and tail pointers
of the DBR ring along with the time at which each buffer is received and
replenished. All modules that use DBR framework can use this
infrastructure. Issues that are specific to tail index movement from
the target can be identified with this debug infrastructure.

UNII-1 and UNII-2A are represented by bits 0x1 and 0x2 respectively in
this implementation. The user space command should set the bits by
applying the following algorithm:
1) To disable only the UNII-1 band channels, set the value as 0x1.
2) To disable only the UNII-2A band channels, set the value as 0x2.
3) To disable both the UNII-1 and UNII-2A band channels, set the
value as 0x3.
4) To restore both the UNII-1 and UNII-2A band channels, set the
value as 0x0.

When SAP do connection with first Ref-STA or dis-connection with
last Ref_STA, wlan host need to re-configure REO Dst ring control
register. one of the register offset is 0xA38004, host need to write
remap window register (offset 0x310C) with value 0x14 first, but
sometimes this remap window writing not work, so just use the remap
window value 0x3F left by last writing, final Dst register offset will
be 0x1FB8004 which is out of valid range.
Find that if we read back the remap window after writing is done,
remap window writing failure issue is gone. as a WAR, check register
writing result for this specific register REO_R0_DST_RING_CTRL_IX_0

SAE key derivation requires use of a secret element, PWE. This
element is deterministically discovered by repeatedly hashing
the password with some additional information until the
resulting hash is the abscissa of a point on the elliptic curve
(for ECC) or by exponentiating the hash digest to a constant to
produce an element (for FFC). This "hunting-and-pecking" loop
method is prone to side channel attacks.
To avoid this, a direct hashing to element technique in SAE is
introduced in IEEE P802.11-REVmd/D3.0. Support new RSNX IEEE
as part of the hash to element PWE derivation. The user space
sends the RSNX IE in the connect request.
Add support for new RSNX IE with element ID 244.

Write into hal register using three floating windows instead of one.
This change is done to avoid frequent window changes for writing into
DP and CE registers. Instead 3 windows are used. One window is statically
mapped to CE block and another window is mapped statically to DP block.
Due to this design there is no need to change the window register to
write into these blocks and write can be done on corresponding window
with single iowrite32. Similar loginc is used for ioread32.
Also modified the hp_addr and tp_addr in initialisation stage so that
hal_write will not have multiple if checks.
