[Buildroot] [PATCH] package/rtl8723ds: fix build failure on PowerPC

[Giulio Benetti]

Add local patch(pending upstream[0]) to fix build failure with PowerPC due
to a package re-defition of get_ra() that is only defined in Linux PowerPC
implementation.

+Subject: [PATCH] rtl8723ds: get_ra() exists only on PowerPC
+
+In PowerPc Linux only get_ra() exists[0] and conflicts with local get_ra()
+that has a completely different purpose. So let's rename local get_ra()
+to wifi_get_ra() to make it different from Linux's get_ra().
