[PATCH -next] x86/cyrix: include header linux/isa-dma.h

[Randy Dunlap]

x86/kernel/cpu/cyrix.c now needs to include <linux/isa-dma.h>
since the 'isa_dma_bridge_buggy' variable was moved to it.

Fixes this build error:

../arch/x86/kernel/cpu/cyrix.c: In function ‘init_cyrix’:
../arch/x86/kernel/cpu/cyrix.c:277:17: error: ‘isa_dma_bridge_buggy’ undeclared (first use in this function)
  277 |                 isa_dma_bridge_buggy = 2;

Fixes: abb4970ac335 ("PCI: Move isa_dma_bridge_buggy out of asm/dma.h")
