net: ftmac100: Cast priv->iobase with uintptr_t
priv->iobase was declared as phys_addr_t which is now a 64-bit
address. In a 32-bit build, this causes the following warning
seen when building ftmac100.c:

riscv: Adjust board_get_usable_ram_top() for 32-bit
When testing QEMU RISC-V 'virt' machine with a 2 GiB memory
configuration, it was discovered gd->ram_top is assigned to
value zero in setup_dest_addr().
While gd->ram_top should not be declared as type `unsigned long`,
which will be updated in a future patch, the current logic in
board_get_usable_ram_top() can be updated to cover both 64-bit
and 32-bit RISC-V.

dm: core: Add late driver remove option
Add another flag to the DM core which could be assigned to drivers and
which makes those drivers call their remove callbacks last, just before
booting OS and after all the other drivers finished with their remove
callbacks. This is necessary for things like clock drivers, where the
other drivers might depend on the clock driver in their remove callbacks.
Prime example is the mmc subsystem, which can reconfigure a card from HS
mode to slower modes in the remove callback and for that it needs to
reconfigure the controller clock.

dm: core: Avoid partially removing devices
At present if device_remove() decides that the device should not actually
be removed, it still calls the uclass pre_remove() method and powers the
device down.

dm: core: Remove children before advising uclass
At present the uclass pre-remove method is called before the children are
removed. But the children may refused to be removed, in whch case the
uclass is in a tricky situation. At present we handle this by calling
the uclass' post_probe() method. But it seems better to avoid doing
anything with the uclass in this case.
Switch the ordering so that we make sure the children can be removed
before advising the uclass.
