i40e: add adminq commands for Rx CTL registers

Add the new opcodes and struct used for asking the firmware to update Rx
control registers that need extra care when being accessed while under
heavy traffic - e.g. sustained 64byte packets at line rate on all ports.
The firmware will take extra steps to be sure the register accesses
are successful.

The registers involved are:
	PFQF_CTL_0
	PFQF_HENA
	PFQF_FDALLOC
	PFQF_HREGION
	PFLAN_QALLOC
	VPQF_CTL
	VFQF_HENA
	VFQF_HREGION
	VSIQF_CTL
	VSILAN_QBASE
	VSILAN_QTABLE
	VSIQF_TCREGION
	PFQF_HKEY
	VFQF_HKEY
	PRTQF_CTL_0
	GLFCOE_RCTL
	GLFCOE_RSOF
	GLQF_CTL
	GLQF_SWAP
	GLQF_HASH_MSK
	GLQF_HASH_INSET
	GLQF_HSYM
	GLQF_FC_MSK
	GLQF_FC_INSET
	GLQF_FD_MSK
	PRTQF_FD_INSET
	PRTQF_FD_FLXINSET
	PRTQF_FD_MSK
