Update the name associated with the RCC drivers to avoid
duplicated name with the driver name.

With this patch the traces displayed with log macro provide a
correct device name.

The rcc device name before the patch is:

 Class     Index  Probed  Driver                Name
-----------------------------------------------------------
 root          0  [ + ]   root_driver           root_driver
 simple_bus    0  [ + ]   simple_bus            |-- soc
 (...)
 nop           0  [ + ]   stm32-rcc             |   |-- rcc at 50000000
 clk           0  [ + ]   stm32mp1_clk          |   |   |-- stm32mp1_clk
 reset         0  [ + ]   stm32_rcc_reset       |   |   `-- stm32_rcc_reset

And they become:
 (...)
 nop           0  [ + ]   stm32-rcc             |   |-- rcc at 50000000
 clk           0  [ + ]   stm32mp1_clk          |   |   |-- rcc at 50000000
 reset         0  [ + ]   stm32_rcc_reset       |   |   `-- rcc at 50000000

The traces is correct:
stm32mp1_clk rcc at stm32mp1_clk: .....
=>
stm32mp1_clk rcc at 50000000: .....
