hw/riscv: Don't add empty bootargs to device tree

Commit 7c28f4da20e5 ("RISC-V: Don't add NULL bootargs to device-tree")
tried to avoid adding *NULL* bootargs to device tree, but unfortunately
the changes were entirely useless, due to MachineState::kernel_cmdline
can't be NULL at all as the default value is given as an empty string.
(see hw/core/machine.c::machine_initfn()).

Note the wording of *NULL* bootargs is wrong. It can't be NULL otherwise
a segfault had already been observed by dereferencing the NULL pointer.
It should be worded as *empty" bootargs.

hw: Replace trivial drive_get_next() by drive_get()

drive_get_next() is basically a bad idea. It returns the "next" block
backend of a certain interface type. "Next" means bus=0,unit=N, where
subsequent calls count N up from zero, per interface type.

This lets you define unit numbers implicitly by execution order. If the
order changes, or new calls appear "in the middle", unit numbers change.
ABI break. Hard to spot in review.

A number of machines connect just one backend with drive_get_next().
Change them to use drive_get() directly. This makes the (zero) unit
number explicit in the code.

Move it to the boards that create these devices. Prior art: commit
eb4f566bbb for device "generic-sdhci", and commit 26c607b86b for
device "pl181".

The device remains not user-creatable, because its users should (and
do) wire up its GPIO chip-select line.

hw/riscv: sifive_u: Make sure firmware info is 8-byte aligned

Currently the firmware dynamic info (fw_dyn) is put right after
the reset vector, which is not 8-byte aligned on RV64. OpenSBI
fw_dynamic uses ld to read contents from 'struct fw_dynamic_info',
which expects fw_dyn to be on the 8-byte boundary, otherwise the
misaligned load exception may happen. Fortunately this does not
cause any issue on QEMU, as QEMU does support misaligned load.

RV32 does not have any issue as it is 4-byte aligned already.
Change to make sure it is 8-byte aligned which works for both
RV32 and RV64.
