Subject: [PATCH] rtl8xxxu: Implement rtl8188eu_init_phy_rf()

Include the table rtl8188eu_radioa_init_table derived from vendor
driver. The vendor table relies on a hack setting RF6052_REG_RCK1 +
RF6052_REG_RCK2 with delays. This workaround is open coded here
instead of modifying the table parsing code.
