[PATCH net-next v2 3/3] net: phy: qcom: qca807x: Support PHY counter

[Luo Jie <quic_luoj@quicinc.com>]

Within the QCA807X PHY operation's config_init() function, enable CRC
checking for received and transmitted frames and configure counter to
clear after being read to support counter recording. Additionally, add
support for PHY counter operations.
