When using SCPI as the PSCI backend, firmware can wake up the CPUs and
cluster from sleep, so CPU idle states are available for the rich OS to
use. In that case, advertise them to the rich OS via the DTB.

Commit e2b18771fc2a0528dda18dbdaac08dd8530df25a ("feat(allwinner):
provide CPU idle states to the rich OS") added functionality to amend
dtb, when SCPI as the PSCI backend is available. But this
functionality is disabled by default even for platforms, that support
it, like A64. As a result rich OS don't get information about
available CPU idle states.
Due to size constraints of A64 platform DEBUG=1 can be built with
dtb amend functionality only with LTO enabled. So ENABLE_LTO is
enabled by default for this platform.
```
aarch64-linux-gnu-ld.bfd: address 0x500dd of build/sun50i_a64/debug/bl31/bl31.elf section `.data' is not within region `RAM'
aarch64-linux-gnu-ld.bfd: BL31 image has exceeded its limit.
aarch64-linux-gnu-ld.bfd: region `RAM' overflowed by 224 bytes
```
To build with ENABLE_LTO=0 and DEBUG=1 it's required SUNXI_AMEND_DTB=0
to explicitly disable dtb amend functionality.
sun50i_r329 SUNXI_AMEND_DTB=1 DEBUG=1 build fails with 'region `RAM'
overflowed by 120 bytes'. To avoid unnecessary RAM consumption on
other resource-constraints platforms (like sun50i_r329)
SUNXI_AMEND_DTB is enabled only on sun50i_a64. Otherwise
On other platforms sunxi_idle_states are empty.
