[RFC PATCH 03/19] riscv: Add ENTRY_ALIGN() macro

[Christoph Muellner]

From: Christoph Müllner <christoph.muellner@vrull.eu>

This patch adds an ENTRY_ALIGN() macro to generate
aligned function symbols in assembly files.
Since the LEAF() macro is a special-case of that,
we change LEAF() to be reflect this.
