In "targets/TARGET_RENESAS" folders, same as Cortex-M targets, I changed the folder structure to combine files that can be shared as RZ/A1 related.
And I renamed the folder name to "TARGET_RZ_A1XX" in order to make commonality explicit.
- "targets/TARGET_RENESAS" folder
<before>
\targets\TARGET_RENESAS\TARGET_RZ_A1H
\targets\TARGET_RENESAS\TARGET_VK_RZ_A1H
<after>
\targets\TARGET_RENESAS\TARGET_RZ_A1XX
