* use start/end label for initialization tables instead of fix values
Signed-off-by: Jens Scharsig <js_at...@scharsoft.de>

I have trace through the code with JTAG. It should be work with
CONFIG_TEXT_BASE = 0x0 and CONFIG_TEXT_BASE=0x10000000.
Changes since first version:
* fix: remove on line to much (thanks Andreas Biessmann)
* fix: add _MTEXT_BASE instead of sub from table end
Changes since 2nd version:
* remove trailing whitespace
