[PATCH 1/1] arm64: dts: ipq5018: Correct uart1_pins pinconf

[hzy]

From: Ziyang Huang <hzyitc@xxxxxxxxxxx>

In pinctrl, the pinconfigs for uart are named "blspX_uartY".
  X is the UART ID. Starts from 1.
    1-6 are in BLSP Block 1.
    7-12 are in BLSP Block 2.
  Y is the index of mux config. Starts from 0.

In dts, the serials are also named "blspX_uartY", but with different logic.
  X is the BLSP Block ID. Starts from 1.
  Y is the uart id inside block.
    In "ipq6018.dtsi" and "ipq8074.dtsi", it starts from 1.
    But in "ipq5332.dtsi" and "ipq9574.dtsi", it starts from 0.

+-----------------+-----------------+-------------+-----------------+
|     Block ID    | ID inside Block |  dts name   | pinconfig name  |
| (Starts from 1) | (Starts from 1) |             |                 |
+-----------------+-----------------+-------------+-----------------+
|        1        |        1        | blsp1_uart1 |   blsp0_uartY   |
|        1        |        2        | blsp1_uart2 |   blsp1_uartY   |
|        1        |        6        | blsp1_uart6 |   blsp5_uartY   |
|        2        |        1        | blsp2_uart1 |   blsp6_uartY   |
|        2        |        6        | blsp2_uart6 |   blsp12_uartY  |
+-----------------+-----------------+-------------+-----------------+

In "ipq5018.dts", "blsp1_uart1" (dts name) is the first serial (confimed
by the address), So its pinconfig should be "blsp0_uart0" (pinconfig name,
use GPIO 20 and 21) or "blsp0_uart1" (pinconfig name, use GPIO 28 and 29).
