kernel: bump 4.19 to 4.19.51

Refreshed all patches.

Altered patches:
- 370-netfilter-nf_flow_table-fix-offloaded-connection-tim.patch
- 220-optimize_inlining.patch
- 640-netfilter-nf_flow_table-add-hardware-offload-support.patch

This patch also restores the initial implementation
of the ath79 perfcount IRQ issue. (78ee6b1a40b5)
It was wrongfully backported upstream initially and got reverted now.

Compile-tested on: cns3xxx, imx6
Runtime-tested on: cns3xxx, imx6

+Subject: [PATCH v2] MIPS: perf: ath79: Fix perfcount IRQ assignment
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Currently it's not possible to use perf on ath79 due to genirq flags
+mismatch happening on static virtual IRQ 13 which is used for
+performance counters hardware IRQ 5.
+
+On TP-Link Archer C7v5:
+
+           CPU0
+  2:          0      MIPS   2  ath9k
+  4:        318      MIPS   4  19000000.eth
+  7:      55034      MIPS   7  timer
+  8:       1236      MISC   3  ttyS0
+ 12:          0      INTC   1  ehci_hcd:usb1
+ 13:          0  gpio-ath79   2  keys
+ 14:          0  gpio-ath79   5  keys
+ 15:         31  AR724X PCI    1  ath10k_pci
+
+ $ perf top
+ genirq: Flags mismatch irq 13. 00014c83 (mips_perf_pmu) vs. 00002003 (keys)
+
+On TP-Link Archer C7v4:
+
+         CPU0
+  4:          0      MIPS   4  19000000.eth
+  5:       7135      MIPS   5  1a000000.eth
+  7:      98379      MIPS   7  timer
+  8:         30      MISC   3  ttyS0
+ 12:      90028      INTC   0  ath9k
+ 13:       5520      INTC   1  ehci_hcd:usb1
+ 14:       4623      INTC   2  ehci_hcd:usb2
+ 15:      32844  AR724X PCI    1  ath10k_pci
+ 16:          0  gpio-ath79  16  keys
+ 23:          0  gpio-ath79  23  keys
+
+ $ perf top
+ genirq: Flags mismatch irq 13. 00014c80 (mips_perf_pmu) vs. 00000080 (ehci_hcd:usb1)
+
+This problem is happening, because currently statically assigned virtual
+IRQ 13 for performance counters is not claimed during the initialization
+of MIPS PMU during the bootup, so the IRQ subsystem doesn't know, that
+this interrupt isn't available for further use.
+
+So this patch fixes the issue by simply booking hardware IRQ 5 for MIPS PMU.

+Changes since v1:
+
+ I've incorporated two comments which I've received on IRC from blogic and
+ I've also reworded the commit message to match the changes in v2 of this
+ patch.
+
+  * use actual hardware perfcount IRQ 5 instead of the virtual IRQ 13
