libc:kernel-headers:Adding IOCTL to change Q6 clock.

Added ioctl to change Q6 clock dynamically
while video decoding. Client can use this
ioctl to increase/decrease Q6 clock depending
on requirement. Once the instance who
requested the increase/decrease closes, Q6
clock adjusts itself depending on new
requirement.
