mtd: cfi_flash: Fix CFI flash driver for 8-bit bus support

This commit is based on that patch from aaron.williams@caviumnetworks.com
with same commit title. pulled the same code changes into current u-boot tree.

http://patchwork.ozlabs.org/patch/140863/
http://lists.denx.de/pipermail/u-boot/2011-April/089606.html

This patch corrects the addresses used when working with Spansion/AMD FLASH chips.
Addressing for 8 and 16 bits is almost identical except in the 16-bit case the
LSB of the address is always 0.  The confusion arose because the addresses
in the datasheet for 16-bit mode are word addresses but this code assumed it was
byte addresses.

I have only been able to test this on our Octeon boards which use either an 8-bit
or 16-bit bus.  I have not tested the case where there's an 8-bit part on a 16-bit
bus.

This patch also adds some delays as suggested by Spansion.

If a part can be both 8 and 16-bits, it forces it to work in 8-bit mode if an
8-bit bus is detected.

Apart from the pulled changes, fixed few minor code cleanups and tested
on 256M29EW, 512M29EW flashes.

(BMP_ALIGN_CENTER) x/y coordinates. Moving the check after the alignment block

* Register accesses must all be 32-bit, so implement custom accessors.

  SDHCI_QUIRK_WAIT_SEND_CMD appears to solve the issues.
* Remove register logging from read*/write* functions.
* Sort out confusion with min/max_freq values passed to add_sdhci().
* Use more descriptive variable names and calculations in IO accessors.

lcd: calculate line_length after lcd_ctrl_init()

When an LCD driver is actually driving a regular external display, e.g.
an HDMI monitor, the display resolution might not be known until the
display controller has initialized, i.e. during lcd_ctrl_init(). However,
lcd.c calculates lcd_line_length before calling this function, thus
relying on a hard-coded resolution in struct panel_info.

Instead, defer this calculation until after lcd_ctrl_init() has had the
chance to dynamically determine the resolution. This needs to happen
before lcd_clear(), since the value is used there.

grep indicates that no code outside lcd.c uses this lcd_line_length; in
particular, no lcd_ctrl_init() implementations read it.
