Subject: [PATCH v2 04/11] net: dsa: microchip: ksz8795: use reg_mib_cnt where possible

The extra define SWITCH_COUNTER_NUM is a copy of the KSZ8795_COUNTER_NUM
define. This patch initializes reg_mib_cnt with KSZ8795_COUNTER_NUM,
makes use of reg_mib_cnt everywhere instead and removes the extra
define.
