drm/i915/guc/slpc: Define and initialize boost frequency
Define helpers and struct members required to record boost info.
Boost frequency is initialized to RP0 at SLPC init. Also define num_waiters
which can track the pending boost requests.
Boost will be done by scheduling a worker thread. This will avoid
the need to make H2G calls inside an interrupt context. Initialize the
worker function during SLPC init as well. Had to move intel_guc_slpc_init
a few lines below to accommodate this.
v2: Add a workqueue to handle waitboost
v3: Code review comments (Ashutosh)
