linux-aspeed: Move to 5.2.1, fix Aspeed i2c and swift FSI GPIOs

This includes security and bug fixes from the 5.2.1 stable release.

The i2c fix removes is required to support existing Qemu models, as we
do not yet have buffer mode support in qemu.

Joel Stanley (2):
      i2c: aspeed: Update to v3 of buffer and dma support
      Revert "ARM: dts: aspeed: add I2C buffer mode support"

Matt Spinler (1):
      ARM: dts: aspeed: swift: Fix FSI GPIOs
