Clean up Makefile, and drop a lot of the config.mk files on the way.
We now also automatically pick all boards that are listed in
boards.cfg (and with all configurations), so we can drop the redundant
entries from MAKEALL to avoid building these twice.

This patch removes the PPC4xx UART driver. Instead the common NS16550
driver is used, since all PPC4xx SoC's use this peripheral device.
The file 4xx_uart.c now only implements the UART clock calculation
function which also sets the SoC internal UART divisors.
All PPC4xx board config headers are changed to use this common NS16550
driver now.
Tested on these boards:
acadia, canyonlands, katmai, kilauea, sequoia, zeus

A number of boards define CONFIG_SYS_SRAM_BASE but fail to define
CONFIG_SYS_SRAM_SIZE which is needed when cleaning up the code that
prints this information with the bdinfo command.
Add the missing deinitions.

This patch fixes some problems for the T3CORP board. Here the list
of the changes:
- Add 600-67 and 677 CPU frequency setting to chip_config
command
- Define CONFIG_DDR_RFDC_FIXED on t3corp:
While using the "normal" auto calibration code, sometimes values for
RFDC were picked (>= T3) that resulted in a non-working U-Boot (hang
upon relocation, while running from SDRAM). With this optimized RFDC
value we can force this register and use the auto-calibration code to
setup the remaining calibration registers.
- Increase sizes of FPGA chips selects
- EBC timing updated OEN=3 for 66 MHz EBC speed
- Change ext. IRQ2 setup to level-low active
- Enable CONFIG_SYS_CFI_FLASH_STATUS_POLL
By defining CONFIG_SYS_CFI_FLASH_STATUS_POLL, DQ7 is polled to detect the
chip busy status. This is now used instead of the data toggle method which
is used historically by default in the common CFI driver. With this change
a problem with not written data is solved on this board, where a 32 byte
block of data is still erased instead of filled with the correct content
after these commands:
=> erase 0xfc100000 +0x1000000
....................................................................
done
Erased 128 sectors
=> cp.b 0x100000 0xfc100000 0x1000000
Copy to Flash... done
=> cmp.b 0x100000 0xfc100000 0x1000000
byte at 0x00d0d6c0 (0x00) != byte at 0xfcd0d6c0 (0xff)
Total of 12637888 bytes were the same
