[PATCH v3 16/29] riscv: Add <bits/pagesize.h>

[Florian Weimer]

The GNU toolchain defaults to 4 KiB as the maximum page size,
and this is also the only page size supported by Linux
(according to arch/riscv/Kconfig; only HAVE_PAGE_SIZE_4KB is used).

There has been a proposal for 64 KiB page sizes:

  [RFC PATCH V1 00/11] riscv: Introduce 64K base page
  <https://lore.kernel.org/linux-riscv/20231123065708.91345-1-luxu.kernel@bytedance.com/>

But this has not been merged, and it would be necessary to rebuild
all binaries anyway due to the toolchain default, so this commit
claims that the page size is fixed at 4096 bytes.
