Building on Pi Pico W

[sfozz]

Couple of build issues when building for this target.

I've added the following to allow the builds to get started

diff --git a/components/mitsubishi_heatpump/climate.py b/components/mitsubishi_heatpump/climate.py
index da16834..b9c4d74 100644
--- a/components/mitsubishi_heatpump/climate.py
+++ b/components/mitsubishi_heatpump/climate.py
@@ -53,6 +53,8 @@ def valid_uart(uart):
         uarts = ["UART0"]  # UART1 is tx-only
     elif CORE.is_esp32:
         uarts = ["UART0", "UART1", "UART2"]
+    elif CORE.is_rp2040:
+        uarts = ["UART0", "UART1"]
     else:
         raise NotImplementedError

Following this I had to add the build options from here but the builds were still failing... so I added the following as suggested by g++

diff --git a/components/mitsubishi_heatpump/espmhp.h b/components/mitsubishi_heatpump/espmhp.h

I'm now getting the following errors, which are well outside of my c++ chops
