[PATCH v2 1/7] wifi: rtw89: use struct rtw89_phy_sts_ie0 instead of macro to access PHY IE0 status

[Ping-Ke Shih <pkshih@xxxxxxxxxxx>]

To be more clear to know where it gets information from PHY IE0 data,
change to use struct and standard le32_get_bits() to access. This doesn't
change logic at all.
