drm/i915: Use intel_gpu_freq() and intel_freq_opcode()

Browse Source 
Replace all the vlv_gpu_freq(), vlv_freq_opcode(),
*GT_FREQUENCY_MULTIPLIER, and /GT_FREQUENCY_MULTIPLIER instances
with intel_gpu_freq() and intel_freq_opcode() calls.

Most of the change was performed with the following semantic patch:
@@
expression E;
@@
(
- E * GT_FREQUENCY_MULTIPLIER
+ intel_gpu_freq(dev_priv, E)
|
- E *= GT_FREQUENCY_MULTIPLIER
+ E = intel_gpu_freq(dev_priv, E)
|
- E /= GT_FREQUENCY_MULTIPLIER
+ E = intel_freq_opcode(dev_priv, E)
|
- do_div(E, GT_FREQUENCY_MULTIPLIER)
+ E = intel_freq_opcode(dev_priv, E)
)

@@
expression E1, E2;
@@
(
- vlv_gpu_freq(E1, E2)
+ intel_gpu_freq(E1, E2)
|
- vlv_freq_opcode(E1, E2)
+ intel_freq_opcode(E1, E2)
)

@@
expression E1, E2, E3, E4;
@@
(
- if (IS_VALLEYVIEW(E1)) {
-  E2 = intel_gpu_freq(E3, E4);
- } else {
-  E2 = intel_gpu_freq(E3, E4);
- }
+ E2 = intel_gpu_freq(E3, E4);
|
- if (IS_VALLEYVIEW(E1)) {
-  E2 = intel_freq_opcode(E3, E4);
- } else {
-  E2 = intel_freq_opcode(E3, E4);
- }
+ E2 = intel_freq_opcode(E3, E4);
)

One hunk was manually undone as intel_gpu_freq() ended up
calling itself. Supposedly it would be possible to exclude
certain functions via !=~, but I couldn't get that to work.

Also the removal of vlv_gpu_freq() and vlv_opcode_freq() compat
wrappers was done manually.
