[Blackfin] arch: remove NOTES from linker script

  add more common defines for output sections

we've had a new line, NOTES, in our linker script, which causes upstream
binutils to complain about "missing phdr".  Currently the only other arch
that uses NOTES is i386, and the patch which added it also added
PHDRS {
	text PT_LOAD FLAGS(5);	/* R_E */
	data PT_LOAD FLAGS(7);	/* RWE */
	note PT_NOTE FLAGS(0);	/* ___ */
}
and a few other modifications to use ":text" and ":data" to the linker
script.

It seems that we don't need NOTES at all, so just remove it.
