Switch to extension board detection using pci_find_device()
instead of detecting by i2c access to EEPROM device on
extension board.
This is a cleaner detection method since EEPROM addresses
can be different on different board revisions. This also
avoids "i2c_read: failed to address chip" error messages
in the boot log on boards without extension board which
may confuse users.

On newer rev5 hardware the extension board EEPROM I2C address
has been changed to 0x54. Make this I2C address configurable
depending on CONFIG_DIGSY_REV5 so that extention board presence
detection works correctly on newer hardware.

Add detection and initialisation for graphic extension board
and support splash screen when booting. Enable "bmp" command
in the board configuration and provide "disp" command to
be able to switch the display on/off.

A large number of boards incorrectly used getenv() in their board init
code running before relocation. In some cases this caused U-Boot to
hang when certain environment variables grew too long.
Fix the code to use getenv_r().

If no Flash is connected to cs1, Linux crashes, because
reg entries are not correct adapted.
Following fix is needed:
- swap base addresses in CONFIG_SYS_FLASH_BANKS_LIST, as
flash bank 1 is on chipselect 0 and flash bank 2 on
chipselect 1
- call fdt_fixup_nor_flash_size() from ft_board_setup()

difference to previous board version:
- M29W128GH flash from Numonyx
- SDRAM ISSI IS45S16800 (Option A2 105°C)
- rev5 uses RTC RV-3029-C2
- update cs0 and cs1 baseaddr and length
depending on the detected flash size.
- added Werner Pfister <Pfister_Werner@intercontrol.de>
as maintainer for the digsy board variants
- As the M29W128GH needs a special flash_cmd_reset()
document that in the new file doc/README.cfi.
- move "#endif /* CONFIG_CMD_IDE */" to the right place
- remove LOWBOOT config option for digsy_mtc and digsy_mtc_rev5
boards
- change doc/README.cfi as Stefan Roese suggested
