qseecom: Add new IOCTLs to support secure UI feature

User space sends the buffer to TZ to use it for secure UI features.
Buffer shall be protected based on the use case, two APIs are
introduced to support this feature.

- QSEECOM_IOCTL_SEND_MODFD_RESP: is called to modify the listener
response data with physical address replaced at a mentioned offset,
so as to be usable by TZ. Option to protect &/ unprotect the buffer
is provided from user space (based on use case).

- QSEECOM_IOCTL_UNPROTECT_BUF: is called to explicitly unprotect the
protected buffer (use case specific).

qseecom: Copy userspace buffer into kernel space before dereferencing

ION memory is used for user space to kernel space data passing.
This is directly accessible in kernel. But, if the IOCTL is called
from user space without using User space library, then data might
be pointing to some other memory location, in which case, it would
not be possible to dereference this location in kernel & hence it
would be accessing invalid memory.

qseecom: Fix error handling path in receive_req()

This patch fixes the error handling path in receive_req() function
called from userspace. Issue seen if user is calling the receive_req
function without calling the listener registration. qseecom_find_svc()
should return NULL if there are no services found.

ARM: dts: msm: Modify bus vector for RNG client on msm8974

Modify the RNG (Random Number Generator) bus vector to use a different
originating master id, this change helps alleviate some slowdowns in boot
time noticed in targets where CPU is artificially bus throttled below a
threshold frequency.

devfreq: governor_cpubw_hwmon: Remove sample_ms and fix round up of freq

devfreq already provides a sysfs interface for changing polling/sampling
period. So, there is no need for the governor to separately expose
sampling_ms. Also, sampling_ms had to be explicitly updated whenever
polling_ms was updated for the governor to function correctly. Make the
interface simpler by combining sample_ms with polling_interval control
provided by devfreq.

The rounding of freq to multiples of bw_step is unnecessary since the
devfreq device already does the rounding to the next valid level. Rounding
of AB to multiples of bw_step is still necessary since it's a vote that's
summed up and doesn't have a direct 1-to-1 mapping to frequencies.

Also update default bw_step to 190 MB/s instead of 200 MB/s to account for
the fact that MB/s to MHz conversion needs to take into account the
difference in the meaning of M (2^20 vs 10^6) between MB and MHz. Similarly
also update io_percent to 16.
