e300: increase CONFIG_SYS_BOOTMAPSZ to allow booting large kernels

Newer Linux kernels can overrun the initial memory window used for
booting with their BSS area. When this happens, they overwrite the FDT
and silently fail to boot.

On e300 CPUs, the Linux kernel uses an initial BAT covering the first
256MB of RAM. See arch/powerpc/kernel/head_32.S for details. Increase
the value of CONFIG_SYS_BOOTMAPSZ to accommodate the maximum value
allowed by Linux. This will allow very large kernels to boot.

Remove unused CONFIG_SERIAL_SOFTWARE_FIFO feature

This patch removes the completely unused CONFIG_SERIAL_SOFTWARE_FIFO
feature from U-Boot. It has only been implemented for PPC4xx and was not
used at all. So let's remove it and make the code smaller and cleaner.

also tested on these boards (albeit with a less accurate
boottime measurement method):

seconds: before after
8349MDS ~2.6 ~2.2
8360MDS ~2.8 ~2.6
8313RDB ~2.5 ~2.3 #nand boot
837xRDB ~3.1 ~2.3

also tested on an 8323ERDB.

v2: also remove the delayed icache enablement assumption in arch ppc's
board.c, and add a CONFIG_MPC83xx define in the ITX config file for
consistency (even though it was already being defined in 83xx'
config.mk).

mpc83xx: retain POR values of non-configured ACR, SPCR, SCCR, and LCRR bitfields

some LCRR bits are not documented throughout the 83xx family RMs.
New board porters copying similar board configurations might omit
setting e.g., DBYP since it was not documented in their SoC's RM.

Prevent them bricking their board by retaining power on reset values
in bit fields that the board porter doesn't explicitly configure
via CONFIG_SYS_<registername>_<bitfield> assignments in the board
config file.

also move LCRR assignment to cpu_init_r[am] to help ensure no
transactions are being executed via the local bus while CLKDIV is being
modified.

also start to use i/o accessors.
