Now that include/config_fallbacks.h define a sane fallback for
CONFIG_SYS_MAXARGS, we can drop the definition of this constant in all
configurations that were using the default value.

We can finally drop TPL_STACK, TPL_TEXT_BASE and TPL_MAX_SIZE off the
whitelist (this time it's really happening!) and migrate the setting
(only used on the RK3368-uQ7 so far) into Kconfig.

To build TPL and SPL stages for the RK3368, we will also need to
enable the SPL_FRAMEWORK.

For the RK3368, we use a multi-stage boot-process consisting of the
following:
1. TPL: initalises DRAM, returns to boot-ROM (which then loads
the next stage and transfers control to it)
2. SPL: a full-features SPL stage including OF_CONTROL and FIT
image loading, which fetches the ATF, DTB and full U-Boot
and then transfers control to the ATF (using the BL31
parameter block to indicate the location of BL33/U-Boot)
3. ATF: sets up the secure world and exits to BL33 (i.e. a full
U-Boot) in the normal world
4. full U-Boot
TPL/SPL and the full U-Boot are built from this tree and need to
run from distinct text addresses and with distinct initial stack
pointer addresses.
This commit sets up the configuration to run:
- TPL from the SRAM at 0xff8c0000 (note that the first 0x1000
are reserved for use by the boot-ROM and contain the SP
when the TPL is entered)
- SPL from DRAM at 0x0
- U-Boot from DRAM at 0x200000

The BootROM of the RK3368 Boot ROM does not initialise cntfrq_el0.
This change defines COUNTER_FREQUENCY, which is used by the AArch64 init
code in arch/arm/cpu/armv8/start.S to set up cntfrq_el0.
If the counter-frequency is not correctly set up, the calculation of
delays using the ARMv8 generic timer can not work correctly.

There are some functions like sdram_size_mb can be re-used for
different rockchip SoCs, just put them into common file.
Add board_get_usable_ram_top() for ram_top init base on
SDRAM_MAX_SIZE.

fixup: 3036 fix for sdram_common
The RK3368 is an octa-core Cortex-A53 SoC from Rockchip.
This adds basic support to chain-load U-Boot from Rockchip's
miniloader.
