riscv: mm: Change attribute from __init to __meminit for page functions
Prepare for memory hotplugging support by changing from __init to
__meminit for the page table functions that are used by the upcoming
architecture specific callbacks.
Changing the __init attribute to __meminit, avoids that the functions
are removed after init. The __meminit attribute makes sure the
functions are kept in the kernel text post init, but only if memory
hotplugging is enabled for the build.
