Enable power saving features on L2 memory

0 (L2_MEM_EN_POWERSAVING_0): Enters power saving mode only when chip is in SUSPEND mode

1 (L2_MEM_EN_POWERSAVING_1): Controlled by L2_MEM_DEEPSLEEP bitfield

Automatically gate off RAM clock when RAM is not accessed.

0 (RAM_AUTO_CLK_GATING_EN_0): disable automatically gate off RAM clock

1 (RAM_AUTO_CLK_GATING_EN_1): enable automatically gate off RAM clock

This bit controls how memory (OCRAM) enters Deep Sleep mode (shutdown periphery power, but maintain memory contents, outputs of memory are pulled low

0 (L2_MEM_DEEPSLEEP_0): No force sleep control supported, memory deep sleep mode only entered when whole system in stop mode (OCRAM in normal mode)

1 (L2_MEM_DEEPSLEEP_1): Force memory into deep sleep mode (OCRAM in power saving mode)
