linux-aspeed: Move to 5.4.39

This includes security and bug fixes from the 5.4.39 stable release.

It also includes a revert of the inital workaround for interrupt
behaviour on AST2600's I2C master as 5.4.39 contains an upstream fix.

      i2c: aspeed: Revert initial IRQ workaround

(From meta-aspeed rev: ac403399d5fbed4eba4a1587c9cfc2bb30cfd07a)
