uboot-mediatek: update to v2023.04

Update to next U-Boot timed release.
Remove now obsolete patch
100-01-board-mediatek-add-more-network-configurations.patch
Default IP addresses are now dealt with in Kconfig, no longer in board-
specific C header files.

Add patches to restore ANSI support in bootmenu which was broken upstream,
always use high-speed mode on serial UART for improved stability and fix
an issue with pinconf not being applied on MT7623 resulting in eMMC
being inaccessible when booting from micro SD card.

In order to keep the size of the bootloader on MT7623 below 512kB remove
some unneeded commands on both MT7623 boards.

Tested on:
 * BananaPi BPi-R2 (MT7623N)
 * BananaPi BPi-R3 (MT7986A)
 * BananaPi BPi-R64 (MT7622A)
 * Linksys E8450 (MT7622B)

+Subject: [PATCH] pinctrl: mediatek: set R1/R0 in case pullen/pullsel succeeded

+Commit dafe0fbfb0f3 ("pinctrl: mediatek: rewrite mtk_pinconf_set and
+related functions") changed the logic deciding to set R0 and R1
+registers for V1 devices.
+
+Before:
+	/* Also set PUPD/R0/R1 if the pin has them */
+	err = mtk_hw_set_value(dev, pin, PINCTRL_PIN_REG_PUPD, !pullup);
+	if (err != -EINVAL) {
+		mtk_hw_set_value(dev, pin, PINCTRL_PIN_REG_R0, r0);
+		mtk_hw_set_value(dev, pin, PINCTRL_PIN_REG_R1, r1);
+	}
+
+After:
+	/* try pupd_r1_r0 if pullen_pullsel return error */
+	err = mtk_pinconf_bias_set_pullen_pullsel(dev, pin, disable, pullup,
+						  val);
+	if (err)
+		return mtk_pinconf_bias_set_pupd_r1_r0(dev, pin, disable,
+						       pullup, val);
+
+Tracing mtk_pinconf_bias_set_pullen_pullsel shows that the function
+always either returns 0 in case of success or -EINVAL in case any error
+has occurred. Hence the logic responsible of the decision to program R0
+and R1 has been inverted.
+
+This leads to problems on BananaPi R2 (MT7623N) when booting from
+SDMMC, it turns out accessing eMMC no longer works since
+U-Boot 2022.07:
+
+MT7623> mmc dev 0
+Card did not respond to voltage select! : -110
+
+The problem wasn't detected for a long time as both eMMC and SDMMC work
+fine if they are used to boot from, and hence R0 and R1 were already
+setup by the bootrom and/or preloader.
+
+Fix the logic to restore the originally intended and correct behavior
+and also change the descriptive comment accordingly.
