nios2: define _end in link script

Since commit 44c6e6591cb451ae606f8bde71dd5fb7b4002544
"rename _end to __bss_end__" , the _end was removed.
But we need it now for separated device tree control,

The _end is used by fdtdec_setup() to find the blob.

nios2: remove gp assignments in link script

Since we don't use gp for small data with option "-G0",
we use gp as global data pointer. The _gp location is
not needed.

The ALIGN(16) was for gp only.

As we will use u-boot-dtb.bin, the code relocation range

nios2: enlarge the code relocation range

As we will use u-boot-dtb.bin, the code relocation range
should be adjusted to accommodate the additional dtb.
It might be overkilled to look into dtb header to find the
dtb size, so we will simply use CONFIG_SYS_MONITOR_LEN.

nios2: BSS should be cleared only after board_init_f

As dtb in u-boot-dtb.bin overlapped the BSS section,
we should delay the clearing of BSS until dtb is relocated
in board_init_f().
