rtase: Fix flow control configuration

The hardware has two sets of registers controlling TX/RX flow control.
The effective flow control state is determined by the logical OR of
these two sets of bits.

RTASE_FORCE_TXFLOW_EN and RTASE_FORCE_RXFLOW_EN in RTASE_CPLUS_CMD are
the bits used by the driver to control TX/RX flow control according to
the ethtool pause configuration.

RTASE_TXFLOW_EN and RTASE_RXFLOW_EN in RTASE_GPHY_STD_00 are another
set of TX/RX flow control enable bits. Clear them by default so they do
not keep flow control enabled independently of the driver setting.

With the RTASE_GPHY_STD_00 bits cleared, the effective flow control
state is controlled through RTASE_CPLUS_CMD, so the ethtool setting can
take effect correctly.
