x86/cyrix: include header linux/isa-dma.h

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: 3ab0c04f39d8 ("PCI: Move isa_dma_bridge_buggy out of asm/dma.h")
