ath79: 5.15: fix not exported sym ath79_pll_base

ath79_pll_base was declared as extern but no code exported it.
Anyone including arch/mips/include/asm/mach-ath79/ath79.h and compiled
as a module would break with:

ERROR: modpost: "ath79_pll_base" [drivers/net/ethernet/atheros/ag71xx/ag71xx.ko] undefined!

+Subject: [PATCH] ath79: export ath79_pll_base
+
+This symbol is declared as extern but nobody exported it.
+Any module including arch/mips/include/asm/mach-ath79/ath79.h
+will not build. Without this export, ag71xx.ko will not build
+as a module and the build will fail like this:
+
+ERROR: modpost: "ath79_pll_base" [drivers/net/ethernet/atheros/ag71xx/ag71xx.ko] undefined!
+
+The ath79_pll_base symbol is accessed in the ath79_pll_wr() inline function.
