Subject: [PATCH v6 4/9] KVM: VMX: Move MSR_IA32_VMX_BASIC bit defines to asm/vmx.h

From: Xin Li <xin3.li@intel.com>

Move the bit defines for MSR_IA32_VMX_BASIC from msr-index.h to vmx.h so
that they are colocated with other VMX MSR bit defines, and with the
helpers that extract specific information from an MSR_IA32_VMX_BASIC value.

Opportunistically use BIT_ULL() instead of open coding hex values.

Opportunistically rename VMX_BASIC_64 to VMX_BASIC_32BIT_PHYS_ADDR_ONLY,
as "VMX_BASIC_64" is widly misleading.  The flag enumerates that addresses
are limited to 32 bits, not that 64-bit addresses are allowed.
