Reworked BCM_TCS_CMD macro in order to fix warnings from sparse:
drivers/clk/qcom/clk-rpmh.c:270:28: warning: restricted __le32 degrades to integer
drivers/clk/qcom/clk-rpmh.c:270:28: warning: restricted __le32 degrades to integer
While at it, used le32_encode_bits which made the code easier to
follow and removed unnecessary shift definitions.

Changes in v3:
- align the macro lines better
Changes in v2:
- use le32_encode_bits instead of u32_encode_bits with a cpu_to_le32 on
the fields; this however ment we need to force cast the le32 to the
u32 container.
