configs/freescale_p1010rdb_pa: remove U-Boot build

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.

-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

-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).

 The fast way is to tftp transfer the files via one of the network interfaces.
