pass: hal: Replace the function to get initial maximum frequency

The current maximum frequency is used for saving initial data of
frequency. However, it is affected by other factor such as thermal
throttling, thus the initial value can be lower than expected.
To prevent this problem, the available maximum frequency will be
used to get initial frequency data.
