Subject: [PATCH] Drivers: hv: vmbus: include header for get_irq_regs()

On !RT the header file get_irq_regs() gets pulled in via other header files. On
RT it does not and the build fails:

    drivers/hv/vmbus_drv.c:975 implicit declaration of function ‘get_irq_regs’ [-Werror=implicit-function-declaration]
    drivers/hv/hv.c:115 implicit declaration of function ‘get_irq_regs’ [-Werror=implicit-function-declaration]

Add the header file for get_irq_regs() in a common header so it used by
vmbus_drv.c by hv.c for their get_irq_regs() usage.
