arm:samsung:trats:fix: Restore proper orientation of TRATS's LCD panel

Before setting: mipi_lcd_device.reverse_panel = 1, the Trats's LCD panel
was flipped by 180 degrees.

The flip was caused by following change:
Exynos: Change get_timer() to work correctly
SHA1: 3d00c0cb96ff93a929700b80d89cb905e5ab5315

This commit fixed udelay(), which is necessary (due to HW LCD controller
oddity) for mipi-dsi correct operation. As a result the display orientation
has been switched.

As a follow up, the hwrevision() function has been removed, since it was
used only in this particular place.

Test HW: Trats Exynos4210 rev 0.
