The change into Hyp mode is done by doing an exception return from Mon. This doesn't work with current QEMU. The problem is that in bad_mode_switch() we refuse to allow the change of mode. Note that bad_mode_switch() is used to do validation for two situations: (1) changes to mode by instructions writing to CPSR.M (ie not exception take/return) -- this corresponds to the Armv8 Arm ARM pseudocode Arch32.WriteModeByInstr (2) changes to mode by exception return Attempting to enter or leave Hyp mode via case (1) is forbidden in v8 and UNPREDICTABLE in v7, and QEMU is correct to disallow it there. However, we're already doing that check at the top of the bad_mode_switch() function, so if that passes then we should allow the case (2) exception return mode changes to switch into Hyp mode. We want to test whether we're trying to return to the nonexistent "secure Hyp" mode, so we need to look at arm_is_secure_below_el3() rather than arm_is_secure(), since the latter is always true if we're in Mon (EL3).

These side-effects are largely handled in pmu_op_start/finish functions which can be called before and after the state is saved/restored. By doing this and adding raw read/write functions for the affected registers, we avoid migration-related inconsistencies.

Most important registers are those related to DRAM initialization and calibration, where SPL initiates process and waits until certain bit is set/cleared. This patch adds these registers, initializes reset values from user's guide and updates state of registers as SPL expects it.

Only master-mode functionality is implemented. The SPL boot for Cubieboard expects AXP209 PMIC on TWI0/I2C0 bus, so this is first part enabling the TWI/I2C bus operation. Since both Allwinner A10 and H3 use the same module, it is added for both boards. Docs are also updated for Cubieboard and Orangepi-PC board to indicate I2C availability.
