treewide: replace with error() with pr_err()

treewide: replace with error() with pr_err()

U-Boot widely uses error() as a bit noisier variant of printf().

This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:

# define __compiletime_error(message) __attribute__((error(message)))

This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux. (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)

Let's convert error() into now treewide-available pr_err().

Done with the help of Coccinelle, excluing tools/ directory.

The semantic patch I used is as follows:

// <smpl>
@@@@
-error
+pr_err
(...)
// </smpl>

drivers/video/am335x-fb: Properly point framebuffer behind palette

The DMA was outputting the palette on the screen because the base
for the DMA was not after the palette. In addition to that, the ceiling was
also too high, this led that the output on the screen was shifted.

NOTE: According to the TRM, even in 16/24bit mode a palette is required
in the first 32 bytes of the framebuffer.

"In this mode, the LCDC will assume all information is data and thus you
need to ensure that the DMA points to the first pixel of data and not the
first entry in the frame buffer which is the beginning of the 512 byte
palette."

According to the TRM the uppermost byte will be ignored when
LCD_TFT_24BPP_UNPACK is set.

The switch logic is based on the Linux kernel tilcdc driver:
drivers/gpu/drm/tilcdc/tilcdc_crtc.c: lines 407 through 419
(kernel was checked out at commit: bcc981e9ed8)

drivers/video/am335x-fb: Fix bits for LCD_PALMODE_RAWDATA definition

According to the TRM you have to set bits [21:20] to 0b10 for RAW mode, so
(0x10 << 20) is obviously wrong here.

drivers/video/am335x-fb: Add possibility to wait for stable power/picture

Often on boards exists a circuit which switches power on/off to LCD display.
Due to the need of limiting the in-rush current the output voltage from this
circuit rises "slowly", so it is necessary to wait a bit (VCC ramp up time)
before starting output on LCD-pins.
This time is specified in <n> ms within the panel-settings, called "pup_delay"

Further some LCDs need a couple of frames to stabilize the image on it.
We have now the possibility to wait some time after starting output on LCD.
This time is also specified in <n> ms within panel-settings, called "pon_delay"
