[PATCH] mpc83xx: fix NAND bootstrap too big error

[Kim Phillips]

commit 167cdad1372917bc11c636c359aad02625291fa9 "SERIAL: Enable
port-mapped access" inadvertently broke 83xx nand boards by
converting NS16550_init to use io accessors, which expanded
the size of the generated code.

this patch fixes the problem by removing icache functions from
the nand builds, which somewhat follows the icache implementation
commit 1a2e203b31d33fb720f2cf1033b241ad36ab405a "mpc83xx: turn on
icache in core initialization to improve u-boot boot time" took.
