fix rocm get_device name

[divakar-amd]

Problem: Different machines resort to different names. This particularly creates confusion for moe config files.

Using amdsmi api:
product_name for mi308 can result in "MI300X" (see issue-1 below)
market_name seems somewhat better, though not perfect (see issue-2 below)
 
Proposing: use 'market_name' && hard-code names for mi308 & mi300

from amdsmi import *
amdsmi_init()
h = amdsmi_get_processor_handles()[0]
print(amdsmi_get_gpu_asic_info(h))
print(amdsmi_get_gpu_board_info(h))

MI308:
    hjbog2:
        - 'market_name': 'MI308X'
        - 'product_name': 'AMD Instinct MI308X OAM'

    smc300x:
        - 'market_name': 'MI308X'
        - 'product_name': 'AMD Instinct MI300X OAM'  <--- issue-1

    banff-s74:
        - 'market_name': 'AMD Instinct MI308X OAM'  <--- issue-2 | instead of just 'MI308X'
        - 'product_name': 'AMD Instinct MI308X OAM'

MI300:
    s65:
        - 'market_name': 'AMD Instinct MI300X'
        - 'product_name': 'AMD Instinct MI300X OAM'

    s73:
        - 'market_name': 'AMD Instinct MI300X'
        - 'product_name': 'AMD Instinct MI300X OAM'
