Add a check to intel_dp_dpms() to skip setting the DP's DPMS mode if
the current mode is the same as the new one.

There is an error in i915_read_blc_pwm_ctl, where the register values
are not being copied correctly. BLC_PWM_CTL and BLC_PWM_CTL2 are
getting mixed up. This patch fixes that so that saveBLC_PWM_CTL2 and
not saveBLC_PWM_CTL is copied to the BLC_PWM_CTL2 register.

Use 0x1000 as the default backlight PWM max value and period. This is
passed in as a module parameter to i915_drv and is used to program the
PWM registers. It can be set to other values based on the needs of each
system.

Do you expect to have other settings that you won't get from a VBIOS VBT
(e.g. video timings, dual refresh info)?
If so, it might make more sense to have an alternate init path for the
non-VBT values to replace all the VBT parsing. I.e. if your DMI match
happens, call into something other
for systems that are to use the non-alternate frequency. Currently,
only Lumpy is on the list.
