armv7: add reset timeout to identify_nand_chip

identify_nand_chip hangs forever in loop when NAND is not present.
As IGEPv2 comes either with NAND or OneNAND flash, add reset timeout
to let function fail gracefully allowing caller to know NAND is
not present. On NAND equipped board, reset succeeds on first read,
so 1000 loops seems to be safe timeout.
