[PATCH] Include __param section in read-only data range

The param section is an array of "kernel_param" structures, storing only
constant data: pointer to name, permission of the variable pointed to by
(void *)arg and pointers to set/get methods.

Move end_rodata down to include __param section in the read-only range used
by CONFIG_DEBUG_RODATA.
