xtensa: clear all DBREAKC registers on start
[ Upstream commit 7de7ac785ae18a2cdc78d7560f48e3213d9ea0ab ]
There are XCHAL_NUM_DBREAK registers, clear them all.
This also fixes cryptic assembler error message with binutils 2.25 when
XCHAL_NUM_DBREAK is 0:
as: out of memory allocating 18446744073709551575 bytes after a total
of 495616 bytes
