Memory: Fix potential validator error

"Other" and "Unknown" are not valid Redfish MemoryDeviceType
values.

Do correct converting D-Bus enum to redfish.

Straight mapping (D-Bus and Redfish both contain the same name):
DDR
DDR2
DDR3
DDR4
DDR4E_SDRAM
LPDDR4_SDRAM
LPDDR3_SDRAM
DDR2_SDRAM_FB_DIMM
DDR2_SDRAM_FB_DIMM_PROBE (no E on the end of the d-bus name)
DDR_SGRAM
ROM
SDRAM
EDO
FastPageMode
PipelinedNibble
Logical
HBM
HBM2

The following D-Bus values are not mapped:
Other
Unknown
DRAM
EDRAM
VRAM
SRAM
RAM
FLASH
EEPROM
FEPROM
EPROM
CDRAM
ThreeDRM
RDRAM
FBD2
LPDDR_SDRAM
LPDDR2_SDRAM

The following Redfish values don't have a mapping to:
"DDR4_SDRAM"
"DDR3_SDRAM"
"DDR_SDRAM"
"DDR2_SDRAM"

Saw this because not setting the MemoryType so defaulting to
"Other" and had removed the logic to leave off all other memory
properties when MemorySizeInKB is 0 (commit above).

IBM systems are not setting MemorySizeInKB so it is defaulting to 0
hence why this validator error has not been seen in CI.

The validator error was "ERROR - MemoryDeviceType: Invalid Enum value
'Other' found, expected ['DDR', 'DDR2', 'DDR3', 'DDR4', 'DDR4_SDRAM',
'DDR4E_SDRAM', 'LPDDR4_SDRAM', 'DDR3_SDRAM', 'LPDDR3_SDRAM', 'DDR2_SDRAM',
'DDR2_SDRAM_FB_DIMM', 'DDR2_SDRAM_FB_DIMM_PROBE', 'DDR_SGRAM',
'DDR_SDRAM', 'ROM', 'SDRAM', 'EDO', 'FastPageMode', 'PipelinedNibble',
'Logical', 'HBM', 'HBM2']"

Tested: Passes the validator. Sent this property on D-Bus to different values.
