kernel: bump 4.14 to 4.14.51

The sender domain has a DMARC Reject/Quarantine policy which disallows
sending mailing list messages using the original "From" header.

To mitigate this problem, the original message has been wrapped
automatically by the mailing list software.
Refresh patches.

Remove patch that can be reverse applied:
mvebu/patches-4.14/530-ATA-ahci_mvebu-enable-stop_engine-override.patch
mvebu/patches-4.14/531-ATA-ahci_mvebu-pmp-stop-errata-226.patch

Update patch that no longer applied:
ipq806x/patches-4.14/0035-clk-mux-Split-out-register-accessors-for-reuse.patch

-Subject: [PATCH] libahci: Allow drivers to override stop_engine
-
-Marvell armada37xx, armada7k and armada8k share the same
-AHCI sata controller IP, and currently there is an issue
-(Errata Ref#226)that the SATA can not be detected via SATA
-Port-MultiPlayer(PMP). After debugging, the reason is
-found that the value of Port-x FIS-based Switching Control
-(PxFBS@0x40) became wrong.
-According to design, the bits[11:8, 0] of register PxFBS
-are cleared when Port Command and Status (0x18) bit[0]
-changes its value from 1 to 0, i.e. falling edge of Port
-Command and Status bit[0] sends PULSE that resets PxFBS
-bits[11:8; 0].
-So it needs save the port PxFBS register before PxCMD
-ST write and restore the port PxFBS register afterwards
-in ahci_stop_engine().
-
-This commit allows drivers to override ahci_stop_engine
-behavior for use by the Marvell AHCI driver(and potentially
-other drivers in the future).

-Subject: [PATCH] ata: ahci: mvebu: override ahci_stop_engine for mvebu AHCI
-
-There is an issue(Errata Ref#226) that the SATA can not be
-detected via SATA Port-MultiPlayer(PMP) with following
-error log:
-  ata1.15: PMP product ID mismatch
-  ata1.15: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
-  ata1.15: Port Multiplier vendor mismatch '0x1b4b'!='0x0'
-  ata1.15: PMP revalidation failed (errno=-19)
-
-After debugging, the reason is found that the value Port-x
-FIS-based Switching Control(PxFBS@0x40) become wrong.
-According to design, the bits[11:8, 0] of register PxFBS
-are cleared when Port Command and Status (0x18) bit[0]
-changes its value from 1 to 0, i.e. falling edge of Port
-Command and Status bit[0] sends PULSE that resets PxFBS
-bits[11:8; 0].
-So it needs a mvebu SATA WA to save the port PxFBS register
-before PxCMD ST write and restore it afterwards.
-
-This patch implements the WA in a separate function of
-ahci_mvebu_stop_engine to override ahci_stop_gngine.
