package/rtl8723ds: change CFLAGS approach

Instead of undefining endiannes CFLAGS let's change the approach.

Let's disable the CONFIG_PLATFORM_I386_PC that is set to y by default
involving the endianness to be set to little. This way we can set the
CFLAGS according to architecture with some default define like:

 -DCONFIG_IOCTL_CFG80211
 -DRTW_USE_CFG80211_STA_EVENT
 -Wno-error
