ENGR00218282 MX6Q: fix linker error when more configure enabled.

This commit fix the linker error when enable more function(like CONFIG_NAND,
CONFIG_SPASHSCREEN,etc) in uboot ARM2 board, and a possable linker error for
other MX6 boards:

/home/lambert/share/SATA2/R13.3/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/
bin/arm-eabi-ld: section .bss [27831000 -> 278666e7] overlaps section
.rodata [2782387c -> 278609eb]

/home/lambert/share/SATA2/R13.3/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/
bin/arm-eabi-ld: section .rodata.str1.1 [278609ec -> 27867803] overlaps
section .bss [27831000 -> 278666e7]

One issue here is:
A recent gcc added a new unaligned rodata section called '.rodata.str1.1',
which needs to be added the the linker script.  Instead of just adding this
one section, we use a wildcard ".rodata*" to get all rodata linker section
gcc has now and might add in the future.

Another issue is:
The secure boot feature require __hab_data section in uboot linker script,
but it's have a hard coding magic number, but if we enable more code, cause
.text section bigger, it will cross the line, so it report the
first linker error.

This commit disable SECURE_BOOT feature by default for android,
and comments if user want to use this feature, it needs change the
.lds by there configure.
Also, enlarge the magic number that this feature needs to cover
if more code is build in.
