At present get_timer() does not return sane values. It should count up
smoothly in milliscond intervals.

We can change the PWM to count down at 1MHz, providing a resolution
of 1us and a range of about an hour between required get_timer() calls.

Test with command "sf probe 1:0; time sf read 40008000 0 1000".
Try with different numbers of bytes and see that sane values are obtained

H A Dtrats.cbaa8841d6cc8a8cb79e0aee2fe1b360dacc05aaf Mon Jul 15 14:09:50 UTC 2013 Łukasz Majewski <l.majewski@samsung.com> 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.
