mips_mips64: fix minor host endianness bug

Commit 80f1a92bd798 ("mips64: Add generic mips64 target support")
adds a log of the target's program counter in function
mips_mips64_debug_entry() by directly casting the little-endian
buffer in pc->value.
This is going to print an incorrect value on big-endian hosts.

Use the function buf_get_u64() to return the register value.

Not tested on real HW. Issue identified with GCC compiler flag
'-Wcast-align=strict' after change http://openocd.zylin.com/5937/
("target/register: use an array of uint8_t for register's value").
