This change adds a simple implementation of sbi_aligned_alloc(), for future use
in allocating aligned memory for SMMTT tables.

The upcoming SMMTT implementation will require some larger contiguous memory
regions for the memory tracking tables. We plan to specify the memory region
for these tables as a reserved-memory node in the device tree, and then
dynamically allocate individual tables out of this region. These changes to the
SBI heap allocator will allow us to explicitly create and allocate from a
dedicated heap tied to the table memory region.

Previous patch introduced a change that using hart count as the default
number of tlb entries in the fifo. This makes the default tlb fifo size
grow in square with the number of harts. So the default heap size is
not enough to allocate tlb fifo when the hart count is big.
Fixes: 52fd64b ("platform: Uses hart count as the default size of tlb info")
