clk_pmu_freq_controller_load used the default mask and affected
all the clock frequency controllers (CFC) which had their bits
set in the mask. We wish to enable/disable the CFCs in isolation
through debugfs. So we add a parameter(bit_idx) to the function
which will help affect only one CFC at a time

2) Parse VBIOS tables and build boardobj structures for clock frequency
controller.
3) send clock frequency controller data structures to PMU
4) implement public function to send load/unload command to pmu
to enable/disable clock frequency controller support

Modification of the ARBITER clocks to be P-State aware
Up to now the arbiter just considered the whole range
of the GPC and MCLK domains, which could end up on
illegal combinations of MCLK, GPC2CLK, and set the
SYSCLK and XBARCLK domains below their minimum VCO
The following has been implemented:
(1) Modified VF tables to add which PState are
supported on each point.
(2) Return and store the current PState on the
arbiter state.
(3) Modified logic to prevent illegal combinations of
MCLK and GPC2CLK.
(4) Modified logic to prevent setting VF points for
XBAR and SYS domains below VCO limits.
(5) Modified voltage calculation to account for increased
values of XBAR and SYS on some VF points.
(6) Modified arbiter clock target logic to prevent an
application that has not requested a particular VF point
to set target to default targets.
(7) Remove unnecesary mutexes from critical path

JIRA DNVGPU-143
The arbiter is charged with selecting the proper
frequencies when multiple applications submit
simultaneously clock change requests
On the current implementation, the arbiter guarantees
that the selected frequency will be always higher
or equal to the request, as long as the request is
in range.
The current code is not yet realtime friendly, as
requests are not pre-allocated.
Summary of changes:
(1) pstate/vf switch no longer selects boot frequency
(2) changed mclk code change to accept input freq
(3) added arbiter
(4) now a single session can submit concurrent requests
the last request is the one that applies for that
session
(5) modified locking mechanism to reduce lock contention
(6) Added callback to notify the arbiter that the VF
table has changed and is no longer valid (PMU/Thermals
must call this when VF table is invalid)
(7) changed internal API to work with MHz
(8) added debugfs for stats

function was added to retrieve V for F or
F for V for a given clock domain.
Clock domain can be master or slave.
F or V can be intermediate point between two
successive V or F values in VF table.
VF table should be cached before calling this function.
A F value below Fmin will return Vmin.
F > Fmax will return error
A V value above Vmax wil return F max.
A V value below Vmin will return error.
