This commit adds both a 480p input sampling mode and line2x optimized
mode for the PSP's 480x272 picture. The line2x optimized mode is enabled
automatically when the sampling mode is selected.
When in-game, the PSP outputs a letterboxed 480p picture. The active
portion of the screen is 480x272, but is treated as 480p (480x720).
In addition, a line2x optimized mode is added which produces a 960x544
output picture, which if desired the top + bottom pixels can be dropped
producing a 960x540 (qHD) picture.
To generate a qHD picture, use the following settings:
V. Active: 270
V. Backporch: 135
This change allows highly letterboxed content (e.g. the PSP's 480x272
picture in a 720x480 frame) to be "zoomed" to a full screen picture by
treating the letterbox as horizontal and vertical backporch.

* fix clock selection function implementation
* add support for ALC filter configuration
* add coarse clamp LPF selection
* add support for clamp/ALC offset
* replace all clock muxes with a single cycloneive_clkctrl to minimize skew
* use a single dynamically configured PLL to comply with cycloneive_clkctrl
* fix direct sampling phase adjustment while in sampling menu
* wrap around sampling phase value in menu
* always display full samplerate value in menu
* enable direct loading of profile 10 and higher
Cycle through inputs until sync is found or limit has been reached.
RGsB or YPbPr defaults can be set per input.
Stay on current physical input for a short time when sync is lost.
