configs/freescale_p1010rdb_pa: remove U-Boot build

Browse Source 
Binutils was locked down to 2.24 because U-Boot 2014.01 didn't build
with more recent binutils. However, this doesn't work anymore because
binutils 2.24 is deprecated.

Current U-Boot 2016.09.01 does build successfully, but we don't have a
board anymore to test it.

Since updating U-Boot is generally not needed anyway, we just remove
the U-Boot support.

******************** WARNING ********************
The compiled U-Boot binary is intended for NOR flash only!
It won't work for NAND or SPI and will brick those bootloaders!
Also don't go playing around with different U-boot versions or flash targets
unless you've got the necessary hardware and/or know-how to unbrick your kit.
2014.01 is known good for NOR on the P1010RDB-PA kit.
Freescale released a revised version of the kit with a faster processor and
some other hardware changes named P1010RDB-PB. U-Boot needs to be configured
differently for this kit hence this default config WILL NOT WORK.
This is ONLY related to U-Boot, otherwise the configuration is the same,
you can perfectly use the generated kernel and rootfs.
IF you want to build an U-Boot for the new kit just change
BR2_TARGET_UBOOT_BOARDNAME from P1010RDB-PA_NOR to P1010RDB-PB_NOR.
!!!!! THIS IS COMPLETELY UNTESTED BY BR DEVS SO YOU ARE ON YOUR OWN !!!!!
If it works we'd like to know so drop an email to the mailing list. Thanks.
If your kit doesn't mention PA nor PB in their shipping inventory then it's
the old version (PA).

You'll need to program the files created by buildroot into the flash.
The fast way is to tftp transfer the files via one of the network interfaces.

from the u-boot prompt instead of the "tftp ..." commands stated below.
Beware that serial console file transfers are quite slow!
Remember to set the P1010RDB switches to NOR boot if you want to use
your newly built U-Boot.
1. Program the new U-Boot binary to NOR flash (optional)
If you don't feel confident upgrading your bootloader then don't do it,
it's unnecessary most of the time.
