If actual_freq of gpu is not updated when a gpu floor
is set, TZ is unaware of the gpu frequency change and
computations are based on an incorrect value. By setting
actual_freq, TZ is notified of the new gpu frequency at
the next idle exit.

It is desirable for performance reasons to be able to run dcvs
with different algorithm parameters depending on the number of
CPUs that are online. The algorithm parameters are already replicated
per-CPU, but all CPUs operate in DCVS with the same parameters at
any given time.
These per-CPU parameters now correspond to the total number of CPUs
online. For example, if 2 CPUs are online, the algorithm parameters
for CPU2 are used.

CPU frequencies can differ between different revisions, so create
the table of cpu frequencies dynamically based on data from
acpuclock rather than using a fixed table.
Some of the data in the table comes from sync points that will be
implemented between CPU and GPU frequencies. The sync points are
defined here, but the sync implementation itself will come in a
subsequent commit.

It is useful to be able to toggle at runtime whether

adds a sysfs node per core which when read returns a list

is enabled or not.

With 8974, bandwidth requests are exceeding integer size.
Update ab and ib to ensure values over 4Gbps can be requested.
For 64-bit support, there are four changes in this patch:
Changes in the bus driver structures and functions to
update ab and ib values to uint64.
Updates in client drivers to ensure that the bus APIs
are called with the right types.
Updates to the device-tree. Device-tree nodes don't
provide a clean mechanism to read a combination of u32
and u64 variables within the same property name. So, the
ab and ib values must be specified in kbps instead of
bytes/sec from the device tree. The bus driver function
will convert the ab and ib values read from device-tree
to Mbps.
Change the existing property names to make them consistent
with the convention used by the new property name, which
abides to the Device Tree convention.

With use of the QSB clock source recently eliminated, only one
input of the secondary clock MUX is used on any target. Since
there is overhead involved reprogramming this MUX when changing
the CPU and L2 frequencies, change the code to just program the
MUX at boot. Most noticeably, this removes a 1us delay from
every CPU and L2 frequency switch.

Correct the efuse address base and offset for 8974. Since the offset
is now different on 8974 than on other Krait-based targets, it's no
longer possible to hard-code it in acpuclock-krait.c. Instead, move
it into the QFPROM address passed from SoC specific files.
Since the PTE EFUSE is not yet used on 8974 to select different

functional effect.
