Add a function to the bif-core driver which provides a means to
write new BIF data objects into the non-volatile memory (NVM)
of a BIF slave. Also add functions which can be used to
overwrite or delete an existing BIF object.

Update the BIF slave matching criteria so that BIF consumer
drivers can find BIF slaves which contain BIF objects of a
certain type. Also add functions which allow consumers to get
handles for the BIF objects which match specified search
criteria.

Add support in the bif-core driver for enabling and disabling
automatic task triggering for specified tasks. One example of
auto task triggering is the periodic polling method employed by
the BIF slave temperature function to check for high or low
temperature conditions.

Add a length check in the non-volatile memory (NVM) BIF object
parsing function so that it does not attempt to read past the
end of the NVM address space of the BIF slave.

Mark all stub functions in the BIF consumer.h header file with
'static inline' in order to avoid compilation errors in files
that include consumer.h when CONFIG_BIF=n.

Move functions calls which clear PMIC BSI hardware errors and
reset IRQ flags to immediately before BIF transmit calls. This
ensures that the BSI RX and TX blocks are in the correct state
before errors are cleared.

When performing a BIF slave register read of a single register
there is no need to specify a burst read length of 1. All reads
are assumed to be of length 1 unless specified otherwise.
Therefore, remove the redundant RBL1 BIF bus command.

The value QPNP_BSI_MAX_TRANSMIT_CYCLES is used to define the
timeout interval when sending or receiving BIF data words.
The MIPI-BIF specification allows for some skew in the length
of bits received from a slave. A '1' can take up to 3.5 tau_bif
and a '0' can take up to 1.5 tau_bif. Therefore, the maximum word
transmission time can be calculated as follows.
max-transmission-time =
= n(1)_max * t(1)_max + (17 - n(1)_max) * t(0)_max + t(stop)_min
= 8 * 3.5 tau_bif + 9 * 1.5 tau_bif + 4.5 tau_bif
= 46 tau_bif
Change QPNP_BSI_MAX_TRANSMIT_CYCLES to 46 in order to match the
value calculated from the MIPI-BIF specification.

it is communicating with the right chip.
gtp_read_version is modified to gtp_read_fw_version
which reads the firmware version from the controller
and will be used during fw update process.
