Fix the programming of DisplayPort SDP registers primarily related
to Audio enable sequence. This would fix potential issues caused by
read/append/write operations on SDP registers which might corrupt
the parity/data bytes. This would lead to audio issues since the DP
controller would treat the corrupt SDP information as invalid data.

Issue:
When total_steps is updated, after that, copy_from_user
fails with an error, then, i2c_reg_tbl is not allocated.
In this case, when calling msm_actuator_parse_i2c_params,
it lead to out-of-bound memory write.
Fix:
1) Assign total_steps to zero when error from copying.
2) Add NULL pointer check for i2c tbl.

Due to delay of ~3 sec between core reset response
and core init cmd, i2c send fails as NFC controller
goes to deep sleep state if its idle for ~1sec.
Delay caused due to logs in driver probe sequence.
Delay is added after every gpio state change to
ensure, modified value is taken into consideration
and unnecessary delays are removed.

Cuurently as a part of start host, after the block reset we
are performing core init and gadget restart of the dwc3
controller. This causes crash for host only controller where
ep0 and ep1 have not been initialised but are being
dereferenced. Also, HW reinitialisation is not required for
start or restart host routine.

Add support for registering SPI slave controllers using the existing SPI
master framework:
- SPI slave controllers must use spi_alloc_slave() instead of
spi_alloc_master(), and should provide an additional callback
"slave_abort" to abort an ongoing SPI transfer request,
- SPI slave controllers are added to a new "spi_slave" device class,
- SPI slave handlers can be bound to the SPI slave device represented
by an SPI slave controller using a DT child node named "slave",
- Alternatively, (un)binding an SPI slave handler to the SPI slave
device represented by an SPI slave controller can be done by
(un)registering the slave device through a sysfs virtual file named
"slave".
From the point of view of an SPI slave protocol handler, an SPI slave
controller looks almost like an ordinary SPI master controller. The only
exception is that a transfer request will block on the remote SPI
master, and may be cancelled using spi_slave_abort().
