Subject: [PATCH v3] net: ethernet: mtk_ppe: Change PPE entries number to 16K

MT7981,7986 and 7988 all supports 32768 PPE entries, and MT7621/MT7620
supports 16384 PPE entries, but only set to 8192 entries in driver. So
incrase max entries to 16384 instead.

 - Reduced max entries from 32768 to 16384 to keep compatible with MT7620/21 devices.
 - Add fixes tag

Changes since V2:
 - Remove fixes tag (Thanks to Jakub)
