ar71xx: make IRQ fixes target specific

Move the IRQ fix from generic to ar71xx specific.
Other targets like ath79 have specific pathes to delete this code.
This resulted in a build failure on ath79

While at it, wipe the 4.19 version, as ar71xx will never reach this.

-Subject: [PATCH] MIPS: ath79: Fix potentially missed IRQ handling during
- dispatch
-
-If both interrupts are set in the current implementation
-only the 1st will be handled and the 2nd will be skipped
-due to the "if else" condition.
-
-Fix this by using the same approach as done for QCA955x
-just below it.
