[PATCH 2/2] staging: vt6655: Use loop in vt6655_mac_read_ether_addr

[Philipp Hortmann <philipp.g.hortmann@gmail.com>]

Use loop in vt6655_mac_read_ether_addr to avoid multiple
similar statements.

Signed-off-by: Philipp Hortmann <philipp.g.hortmann@gmail.com>

Code for testing:
	for (int i = 0; i < 6; i++){
		mac_addr[i] = ioread8(iobase + MAC_REG_PAR0 + i);
		printk("i = %i\n", i);
	}
Log:
[ 3608.011168] i = 0
[ 3608.011170] i = 1
[ 3608.011172] i = 2
[ 3608.011174] i = 3
[ 3608.011176] i = 4
[ 3608.011178] i = 5
