soc/amd/mendocino: Unmap hash table after usage
Earlier the entire SPI ROM is mapped at the start of verstage and then unmapped at the end of verstage. With CB:74606, this behavior has changed. So unmap the hash table CBFS file after usage. BUG=b:240664755 TEST=Build and boot to OS in Skyrim. Perform cold, warm reboots and suspend/resume cycles for 50 iterations each. Ensured that there is no impact to boot time.
