[PATCH v3 2/2] drm/panel: simple: Add support BOE nv101wxmn51

[Caesar Wang]

10.1WXGA is a color active matrix TFT LCD module using amorphous silicon
TFT's as an active switching devices. It can be supported by the
simple-panel driver.

Read the panel default edid information:

EDID MODE DETAILS
                name = <NULL>
                pixel_clock = 71900
                lvds_dual_channel = 0
                refresh = 0
                ha = 1280
                hbl = 160
                hso = 48
                hspw = 32
                hborder = 0
                va = 800
                vbl = 32
                vso = 3
                vspw = 5
                vborder = 0
                phsync = +
                pvsync = -
                x_mm = 0
                y_mm = 0
drm_display_mode
                .hdisplay = 1280
                .hsync_start = 1328
                .hsync_end = 1360
                .htotal = 1440
                .vdisplay = 800
                .vsync_start = 803
                .vsync_end = 808
                .vtotal = 832

There are two modes in the edid:
Detailed mode1: Clock 71.900 MHz, 216 mm x 135 mm
               1280 1328 1360 1440 hborder 0
                800  803  808  832 vborder 0
               +hsync -vsync
Detailed mode2: Clock 57.500 MHz, 216 mm x 135 mm
               1280 1328 1360 1440 hborder 0
                800  803  808  832 vborder 0
               +hsync -vsync

Add the both edid to support more modes for BOE nv101wxmn51.

Changes in v3:
- As StÃphane commented on https://patchwork.kernel.org/patch/9465911,
  add downclock mode for edid.

Changes in v2:
- fix the vsync_start and vsync_end from the edid.
- change the commit.
