Enable fastboot feature on rk3288.
This path doesn't support the fastboot flash function command entirely. We will hit "cannot find partition" assertion without specified partition environment. Define gpt partition layout in specified board such as firefly-rk3288, then enjoy it!

Changes in v3: - Achieve UOC_CON_OFFSET physical address from DT
Changes in v2: - Achieve the regs_phy from DT - Update comments a little
